AAAS	Triple-A syndrome (achalasia-addisonianism-alacrimia) Triple-A syndrome (achalasia-addisonianism-alacrimia) Descrição da doença: The three specific features of triple-A syndrome are achalasia, Addison disease, and alacrima. Achalasia is a disorder that affects the ability to move food through the esophagus. It can lead to severe feeding difficulties and low blood sugar (hypoglycemia). Addisonism, also known as primary adrenal insufficiency, is caused by abnormal function of the small hormone-producing glands on top of each kidney (adrenal glands). The main features of addisonism include fatigue, loss of appetite, weight loss, low blood pressure, and darkening of the skin. The third major feature of this syndrome is a reduced or absent ability to secrete tears (alacrima). Most people with triple A syndrome have all three of these features, although some have only two. Many of the features of triple A syndrome are caused by dysfunction of the autonomic nervous system. People with the syndrome often experience abnormal sweating, difficulty regulating blood pressure, unequal pupil size (anisocoria), and other signs and symptoms of autonomic nervous system dysfunction (dysautonomia).

AARS	Epileptic encephalopathy, early infantile, type 29 Epileptic encephalopathy, early infantile, type 29 Descrição da doença: Epileptic encephalopathy, early infantile, type 29 (EIEE29) is a form of epileptic encephalopathy, a heterogeneous group of severe childhood onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. EIEE29 patients manifest severe infantile epileptic encephalopathy, clubfoot, absent deep tendon reflexes, extrapyramidal symptoms, and persistently deficient myelination.

AARS2	Combined oxidative phosphorylation deficiency 8; Leukoencephalopathy, progressive, with ovarian failure Combined oxidative phosphorylation deficiency 8; Leukoencephalopathy, progressive, with ovarian failure Descrição da doença: Combined oxidative phosphorylation deficiency 8 (COXPD8) is an autosomal recessive disorder due to dysfunction of the mitochondrial respiratory chain. The main clinical manifestation is a lethal infantile hypertrophic cardiomyopathy, but there may also be subtle skeletal muscle and brain involvement. Biochemical studies show combined respiratory chain complex deficiencies in complexes I, III, and IV in cardiac muscle, skeletal muscle, and brain. The liver is not affected (Gotz et al., 2011). Mutation in the AARS2 gene can also cause progressive leukoencephalopathy with ovarian failure, an autosomal recessive neurodegenerative disorder characterized by loss of motor and cognitive skills, usually with onset in young adulthood. Some patients may have a history of delayed motor development or learning difficulties in early childhood. Neurologic decline is severe, usually resulting in gait difficulties, ataxia, spasticity, and cognitive decline and dementia. Most patients lose speech and become wheelchair-bound or bedridden. Brain MRI shows progressive white matter signal abnormalities in the deep white matter. Affected females develop premature ovarian failure (summary by Dallabona et al., 2014).

AASS	Hyperlysinemia, type 1 and type 2 Hyperlysinemia, type 1 and type 2 Descrição da doença: Hyperlysinemia, type 1 is an autosomal recessive metabolic condition with variable clinical features. Some patients who present in infancy with nonspecific seizures, hypotonia, or mildly delayed psychomotor development have been found to have increased serum lysine and pipecolic acid on laboratory analysis. However, about 50% of probands are reported to be asymptomatic, and hyperlysinemia is generally considered to be a benign metabolic variant (Tondo et al., 2013; Houten et al., 2013).The AASS gene encodes a bifunctional enzyme: lysine alpha-ketoglutarate reductase and saccharopine dehydrogenase. In hyperlysinemia type 1, both enzymatic functions of AASS are defective; in hyperlysinemia type 2, also known as Saccharopinuria, some of the first enzymatic function is retained (Cox, 1985; Cox et al., 1985).

ABCA12	Ichthyosis, congenital, autosomal recessive, type 4A; ICAR, type 4B (harlequin) Ichthyosis, congenital, autosomal recessive, type 4A; ICAR, type 4B (harlequin) Descrição da doença: Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of disorders of keratinization characterized primarily by abnormal skin scaling over the whole body. These disorders are limited to skin, with approximately two-thirds of patients presenting severe symptoms. The main skin phenotypes are lamellar ichthyosis (LI) and nonbullous congenital ichthyosiform erythroderma (NCIE), although phenotypic overlap within the same patient or among patients from the same family can occur (Fischer, 2009). Neither histopathologic findings nor ultrastructural features clearly distinguish between NCIE and LI. In addition, mutations in several genes have been shown to cause both lamellar and nonbullous ichthyosiform erythrodermal phenotypes (Akiyama et al., 2003). At the First Ichthyosis Consensus Conference in Soreze in 2009, the term 'autosomal recessive congenital ichthyosis' (ARCI) was designated to encompass LI, NCIE, and harlequin ichthyosis (ARCI 4B; 242500) (Oji et al., 2010).NCIE is characterized by prominent erythroderma and fine white, superficial, semiadherent scales. Most patients present with collodion membrane at birth and have palmoplantar keratoderma, often with painful fissures, digital contractures, and loss of pulp volume. In half of the cases, a nail dystrophy including ridging, subungual hyperkeratosis, or hypoplasia has been described. Ectropion, eclabium, scalp involvement, and loss of eyebrows and lashes seem to be more frequent in NCIE than in lamellar ichthyosis (Fischer et al., 2000). In LI, the scales are large, adherent, dark, and pigmented with no skin erythema. Overlapping phenotypes may depend on the age of the patient and the region of the body. The terminal differentiation of the epidermis is perturbed in both forms, leading to a reduced barrier function and defects of lipid composition in the stratum corneum (Lefevre et al., 2006).In later life, the skin in ARCI may have scales that cover the entire body surface, including the flexural folds, and the scales are highly variable in size and color. Erythema may be very mild and almost invisible. Some affected persons exhibit scarring alopecia, and many have secondary anhidrosis (Eckl et al., 2005).

ABCA3	Surfactant metabolism dysfunction, pulmonary, type 3 Surfactant metabolism dysfunction, pulmonary, type 3 Descrição da doença: Surfactant dysfunction is a lung disorder that causes breathing problems. This condition results from abnormalities in the composition or function of surfactant, a mixture of certain fats (called phospholipids) and proteins that lines the lung tissue and makes breathing easy. Without normal surfactant, the tissue surrounding the alveoli sticks together (because of a force called surface tension) after exhalation, causing the alveoli to collapse. As a result, filling the lungs with air on each breath becomes very difficult, and the delivery of oxygen to the body is impaired.The signs and symptoms of surfactant dysfunction can vary in severity. The most severe form of this condition causes respiratory distress syndrome in newborns. Affected babies have extreme difficulty breathing and are unable to get enough oxygen.

ABCA4	Stargardt disease type 1; Cone-rod dystrophy type 3 Stargardt disease type 1; Cone-rod dystrophy type 3 Descrição da doença: Stargardt disease type 1 follows an autosomal recessive pattern of inheritance and is caused by pathogenic variants in the ABCA4 gene located on chromosomal region 1p22. The age of onset is infantile. This disease is characterized by progressive central vision loss, mild loss of color vision, delayed dark adaptation and macular atrophy with or without paramacular flecks and degeneration of the underlying retinal pigment ephitelium. The estimated prevalence is 1:8,000-10,000. Mutations in the ABCA4 gene account also for 30 to 60 percent of cases of cone-rod dystrophy that are inherited in an autosomal recessive pattern. The problems associated with this condition include a loss of visual sharpness (acuity), an increased sensitivity to light (photophobia), and impaired color vision. These vision problems worsen over time.

ABCB11	Cholestasis, benign recurrent intrahepatic, type 2; Cholestasis, progressive familial intrahepatic, type 2 Cholestasis, benign recurrent intrahepatic, type 2; Cholestasis, progressive familial intrahepatic, type 2 Descrição da doença: Benign recurrent intrahepatic cholestasis is characterized by intermittent episodes of cholestasis without progression to liver failure. The cholestatic attacks vary in severity and duration and patients are asymptomatic between episodes, both clinically and biochemically (van Mil et al., 2004). Mutation in the ABCB11 gene can also cause cholestasis, progressive familial intrahepatic, type 2, a severe form of liver disease, which typically leads to liver failure. In people with PFIC, liver cells are less able to secrete a digestive fluid called bile. The buildup of bile in liver cells causes liver disease in affected individuals.

ABCB4	Cholestasis, progressive familial intrahepatic, type 3 Cholestasis, progressive familial intrahepatic, type 3 Descrição da doença: Cholestasis, progressive familial intrahepatic, type 3 (PFIC3) is a reversible form of cholestasis that occurs most often in the third trimester of pregnancy and recurs in 45 to 70% of subsequent pregnancies. Symptoms include pruritus, jaundice, increased serum bile salts, and abnormal liver enzymes, all of which resolve rapidly after delivery. However, the condition is associated with fetal complications, including placental insufficiency, premature labor, fetal distress, and intrauterine death. Women with ICP are also susceptible to oral contraceptive-induced cholestasis (OCIC). Ursodeoxycholic acid (UDCA) is an effective treatment for conditions caused by ABCB4 mutations (Pasmant et al., 2012).Mutation in the ABCB4 gene accounts for about 15% of ICP cases (Ziol et al., 2008).

ABCB7	X-linked sideroblastic anemia and ataxia (XLSA/A) X-linked sideroblastic anemia and ataxia (XLSA/A) Descrição da doença: XLSA/A is caused by pathogenic variants in the ABCB7 gene located on chromosomal region Xq13.3. The age of onset is neonatal/infantile. XLSA/A is a rare condition characterized by a blood disorder called sideroblastic anemia and movement problems known as ataxia. This condition occurs only in males. People with X-linked sideroblastic anemia and ataxia have mature red blood cells that are smaller than normal (microcytic) and appear pale (hypochromic) because of the shortage of hemoglobin. This disorder also leads to an abnormal accumulation of iron in red blood cells but does not cause a potentially dangerous buildup of iron in the body. The anemia is typically mild and usually does not cause any symptoms. The prevalence is very rare, estimated at <1:1,000,000.

ABCC8	Hyperinsulinemic hypoglycemia, type 1 (congenital hyperinsulinism); Permanent neonatal diabetes mellitus (PNDM) Hyperinsulinemic hypoglycemia, type 1 (congenital hyperinsulinism); Permanent neonatal diabetes mellitus (PNDM) Descrição da doença: Hyperinsulinemic hypoglycemia, also referred to as congenital hyperinsulinism or familial hyperinsulinism, is the most common cause of persistent hypoglycemia in infancy and is due to defective negative feedback regulation of insulin secretion by low glucose levels. Unless early and aggressive intervention is undertaken, brain damage from recurrent episodes of hypoglycemia may occur (Thornton et al., 1998). Furthermore, some mutations in the ABCC8 gene have been found to cause permanent neonatal diabetes mellitus (PNDM). PNDM is a type of diabetes that first appears within the first 6 months of life and persists throughout the lifespan. This form of diabetes is characterized by high blood sugar levels (hyperglycemia) resulting from a shortage of the hormone insulin. Individuals with PNDM experience slow growth before birth (intrauterine growth retardation). Affected infants have hyperglycemia and an excessive loss of fluids (dehydration) and are unable to gain weight and grow at the expected rate (failure to thrive). In some cases, people with PNDM also have certain neurological problems, including developmental delay and recurrent seizures (epilepsy). This combination of developmental delay, epilepsy, and neonatal diabetes is called DEND syndrome. Intermediate DEND syndrome is a similar combination but with milder developmental delay and without epilepsy. A small number of individuals with PNDM have an underdeveloped pancreas. Because the pancreas produces digestive enzymes as well as secreting insulin and other hormones, affected individuals experience digestive problems such as fatty stools and an inability to absorb fat-soluble vitamins. Most clinical cases for the previous two phenotypes have autosomal recessive inheritance but dominant cases have been detected too. Remarkably, certain mutations in this gene can cause the dominant phenotypes noninsulin-dependent diabetes mellitus and hypoglycemia of infancy, leucine-sensitive.

ACP5	Spondyloenchondrodysplasia with immune dysregulation Spondyloenchondrodysplasia with immune dysregulation Descrição da doença: Spondyloenchondrodysplasia with immune dysregulation (SPENCDI) is an immunoosseous dysplasia combining the typical metaphyseal and vertebral bone lesions of spondyloenchondrodysplasia (SPENCD) with immune dysfunction and neurologic involvement. The skeletal dysplasia is characterized by radiolucent and irregular spondylar and metaphyseal lesions that represent islands of chondroid tissue within bone. The vertebral bodies show dorsally accentuated platyspondyly with disturbance of ossification. Clinical abnormalities such as short stature, rhizomelic micromelia, increased lumbar lordosis, barrel chest, facial anomalies, and clumsy movements may be present (Menger et al., 1989). Central nervous system involvement includes spasticity, mental retardation, and cerebral calcifications, and immune dysregulation ranges from autoimmunity to immunodeficiency. Neurologic and autoimmune manifestations have been observed in different combinations within a single family, suggesting that this disorder may be defined by specific radiographic features but has remarkably pleiotropic manifestations (Renella et al., 2006). Briggs et al. (2016) also noted variability in skeletal, neurologic, and immune phenotypes, which was sometimes marked between members of the same family.

ACSF3	Combined malonic and methylmalonic aciduria Combined malonic and methylmalonic aciduria Descrição da doença: Combined malonic and methylmalonic aciduria (CMAMMA) is a condition characterized by high levels of malonic acid and methylmalonic acid in the body. The signs and symptoms of CMAMMA can begin in childhood. In some children, it causes the blood to become too acidic (ketoacidosis), which can damage the body's tissues and organs. Other signs and symptoms may include involuntary muscle tensing (dystonia), weak muscle tone (hypotonia), developmental delay, an inability to grow and gain weight at the expected rate (failure to thrive), low blood sugar (hypoglycemia), and coma. Other people with CMAMMA do not develop signs and symptoms until adulthood.

ACTA1	Nemaline myopathy 3; Congenital fiber-type disproportion myopathy 1 Nemaline myopathy 3; Congenital fiber-type disproportion myopathy 1 Descrição da doença: Nemaline myopathy is a form of congenital myopathy characterized by abnormal thread- or rod-like structures in muscle fibers on histologic examination ('nema' is Greek for 'thread'). The clinical phenotype is highly variable, with differing age at onset and severity. Muscle weakness typically involves proximal muscles, with involvement of the facial, bulbar, and respiratory muscles (Ilkovski et al., 2001). Attempts at classification of nemaline myopathies into clinical subtypes have been complicated by the overlap of clinical features and a continuous phenotypic spectrum of disease (North et al., 1997; Wallgren-Pettersson et al., 1999; Ryan et al., 2001; Sanoudou and Beggs, 2001). In general, 2 clinical groups can be readily distinguished: 'typical' and 'severe.' Typical nemaline myopathy is the most common form, presenting as infantile hypotonia and muscle weakness. It is slowly progressive or nonprogressive, and most adults achieve ambulation. The severe form of the disorder is characterized by absence of spontaneous movement or respiration at birth, arthrogryposis, and death in the first months of life. Much less commonly, late-childhood or even adult-onset can occur. However, adult-onset nemaline myopathy is usually not familial and may represent a different disease (Wallgren-Pettersson et al., 1999; Sanoudou and Beggs, 2001). Myopathy caused by mutations in the ACTA1 gene can show a range of clinical and pathologic phenotypes. Some patients have classic rods, whereas others may also show intranuclear rods, clumped filaments, cores, or fiber-type disproportion (255310), all of which are nonspecific pathologic findings and not pathognomonic of a specific congenital myopathy. The spectrum of clinical phenotypes caused by mutations in ACTA1 may result from different mutations, modifying factors affecting the severity of the disorder, variability in clinical care, or a combination of these factors (Nowak et al., 1999; Kaindl et al., 2004).

AGK	Cataract 38, autosomal recessive; Sengers syndrome Cataract 38, autosomal recessive; Sengers syndrome Descrição da doença: Cataract 38 is a disease charcaterized by an opacification of the crystalline lens of the eye becoming evident at birth. It frequently results in visual impairment or blindness. Opacities vary in morphology, are often confined to a portion of the lens, and may be static or progressive. In general, the more posteriorly located and dense an opacity, the greater the impact on visual function. Mutation in the AGK gene can also cause Sengers syndrome, an autosomal recessive mitochondrial disorder characterized by congenital cataracts, hypertrophic cardiomyopathy, skeletal myopathy, exercise intolerance, and lactic acidosis. Mental development is normal, but affected individuals may die early from cardiomyopathy (summary by Mayr et al., 2012).

The age of onset is infantile. This metabolic disorder is caused by deficiency of the glycogen debrancher enzyme and is associated with an accumulation of abnormal glycogen with short outer chains. Most patients are enzyme-deficient in both liver and muscle (IIIa), but about 15% are enzyme-deficient in liver only (IIIb) (Shen et al., 1996). These subtypes have been explained by differences in tissue expression of the deficient enzyme (Endo et al., 2006). In rare cases, selective loss of only 1 of the 2 debranching activities, glucosidase or transferase, results in type IIIc or IIId, respectively (Van Hoof and Hers, 1967; Ding et al., 1990).

ALOX12B	Ichthyosis, congenital, autosomal recessive, type 2 Ichthyosis, congenital, autosomal recessive, type 2 Descrição da doença: Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of disorders of keratinization characterized primarily by abnormal skin scaling over the whole body. These disorders are limited to skin, with approximately two-thirds of patients presenting severe symptoms. The main skin phenotypes are lamellar ichthyosis (LI) and nonbullous congenital ichthyosiform erythroderma (NCIE), although phenotypic overlap within the same patient or among patients from the same family can occur (Fischer, 2009). Neither histopathologic findings nor ultrastructural features clearly distinguish between NCIE and LI. In addition, mutations in several genes have been shown to cause both lamellar and nonbullous ichthyosiform erythrodermal phenotypes (Akiyama et al., 2003). At the First Ichthyosis Consensus Conference in Soreze in 2009, the term 'autosomal recessive congenital ichthyosis' (ARCI) was designated to encompass LI, NCIE, and harlequin ichthyosis (ARCI4B; 242500) (Oji et al., 2010).NCIE is characterized by prominent erythroderma and fine white, superficial, semiadherent scales. Most patients present with collodion membrane at birth and have palmoplantar keratoderma, often with painful fissures, digital contractures, and loss of pulp volume. In half of the cases, a nail dystrophy including ridging, subungual hyperkeratosis, or hypoplasia has been described.

The terminal differentiation of the epidermis is perturbed in both forms, leading to a reduced barrier function and defects of lipid composition in the stratum corneum (Lefevre et al., 2006).In later life, the skin in ARCI may have scales that cover the entire body surface, including the flexural folds, and the scales are highly variable in size and color. Erythema may be very mild and almost invisible. Some affected persons exhibit scarring alopecia, and many have secondary anhidrosis (Eckl et al., 2005).

ALS2	Amyotrophic lateral sclerosis, type 2, juvenile; Primary lateral sclerosis, juvenile; Spastic paralysis, infantile onset ascending Amyotrophic lateral sclerosis, type 2, juvenile; Primary lateral sclerosis, juvenile; Spastic paralysis, infantile onset ascending Descrição da doença: Amyotrophic lateral sclerosis (ALS), type 2, juvenile is a very rare severe motor neuron disease characterized by progressive upper and lower motor neuron degeneration causing facial spasticity, dysarthria, and gait disorders with onset before 25 years of age. Mutations in the same gene cause juvenile primary lateral sclerosis (PLSJ) and infantile-onset ascending spastic paralysis (IAHSP). Although primary lateral sclerosis is similar to amyotrophic lateral sclerosis, they are considered to be clinically distinct progressive paralytic neurodegenerative disorders. Following a period of diagnostic confusion, the clinical distinction between ALS and PLSJ became clear and diagnostic criteria established (Pringle et al., 1992). PLS is characterized by degeneration of the upper motor neurons and the corticospinal and corticobulbar tracts, whereas ALS is a more severe disorder characterized by degeneration of both the upper and lower motor neurons. A diagnosis of PLS is essentially one of exclusion (Sotaniemi and Myllyla, 1985; Younger et al., 1988; Yang et al., 2001). Infantile-onset ascending spastic paralysis is an autosomal recessive neurodegenerative disorder characterized by onset in the first years of life of progressive upper and lower motor neuron degeneration resulting in loss of ability to walk in childhood. It initially affects the lower limbs and then ascends to the upper limbs and bulbar muscles, causing dysarthria and dysphagia. Cognition is unaffected (summary by Wakil et al., 2014).

AMACR	Bile acid synthesis defect, congenital, type 4; Alpha-methylacyl-CoA racemase deficiency Bile acid synthesis defect, congenital, type 4; Alpha-methylacyl-CoA racemase deficiency Descrição da doença: Alpha-methylacyl-CoA racemase (AMACR) deficiency is a rare autosomal recessive peroxisomal disorder characterized by adult onset of variable neurodegenerative symptoms affecting the central and peripheral nervous systems. Features may include seizures, visual failure, sensorimotor neuropathy, spasticity, migraine, and white matter hyperintensities on brain imaging. Serum pristanic acid and C27 bile acid intermediates are increased (Smith et al., 2010). AMACR deficiency is caused by mutations in the AMACR gene. AMACR gene mutations that result in a lack of functional AMACR enzyme have also been identified in infants with a life-threatening disorder called congenital bile acid synthesis defect type 4. Babies with this disorder have cholestasis, which is a reduced ability to produce and release a digestive fluid called bile. Cholestasis leads to an enlarged liver (hepatomegaly) and irreversible liver disease (cirrhosis) in the first few months of life. Some researchers consider congenital bile acid synthesis defect type 4 and AMACR deficiency (see above) to be variations of the same disorder. Because most individuals with congenital bile acid synthesis defect type 4 do not survive infancy, it is unclear whether they would have later developed the neurological symptoms seen in adults with AMACR deficiency.

AMER1	Osteopathia striata with cranial sclerosis Osteopathia striata with cranial sclerosis Descrição da doença: Osteopathia striata with cranial sclerosis is an X-linked dominant sclerosing bone dysplasia that presents in females with macrocephaly, cleft palate, mild learning disabilities, sclerosis of the long bones and skull, and longitudinal striations visible on radiographs of the long bones, pelvis, and scapulae (Jenkins et al., 2009). In males, the disorder is usually associated with fetal or neonatal lethality. Occasional surviving males have, in addition to hyperostosis, cardiac, intestinal, and genitourinary malformations. Osteosclerosis in the cranial and facial bones leads to disfigurement and to disability due to pressure on cranial nerves, e.g., deafness. Osteopathia striata is a frequent feature of focal dermal hypoplasia (FDH; 305600).Although early reports of familial cases of this disorder appeared to suggest autosomal dominant inheritance (see, e.g., Horan and Beighton, 1978; Konig et al., 1996), reappraisal of the literature (Behninger and Rott, 2000; Rott et al., 2003) and the finding of a molecular basis for the disorder by Jenkins et al.

AMPD1	Myopathy due to myoadenylate deaminase deficiency Myopathy due to myoadenylate deaminase deficiency Descrição da doença: Myoadenylate deaminase deficiency (MMDD) is an autosomal recessive condition that can manifest as exercise-induced muscle pain, occasionally associated with rhabdomyolysis and/or increased serum creatine kinase, or even infantile hypotonia. However, the finding of homozygous mutations among asymptomatic individuals have suggested to some (e.g., Verzijl et al., 1998) that AMPD1 deficiency may be a harmless entity (Castro-Gago et al., 2011). Genetta et al. (2001) stated that AMPD1 deficiency is the most prevalent genetic disease in humans, the number of people heterozygous approaching 10% of Caucasians and individuals of African descent (Sabina et al., 1989). A small percentage of homozygous-deficient individuals, approximately 1.8% of the population, display symptoms of chronic fatigue and lost productivity as well as a predisposition to stress-related ailments, including heart disease and stroke, according to Genetta et al.

ANOS1	Hypogonadotropic hypogonadism, type 1, with or without anosmia (Kallmann syndrome 1) Hypogonadotropic hypogonadism, type 1, with or without anosmia (Kallmann syndrome 1) Descrição da doença: Congenital idiopathic hypogonadotropic hypogonadism (IHH) is a disorder characterized by absent or incomplete sexual maturation by the age of 18 years, in conjunction with low levels of circulating gonadotropins and testosterone and no other abnormalities of the hypothalamic-pituitary axis. Idiopathic hypogonadotropic hypogonadism can be caused by an isolated defect in gonadotropin-releasing hormone (GNRH; 152760) release, action, or both. Other associated nonreproductive phenotypes, such as anosmia, cleft palate, and sensorineural hearing loss, occur with variable frequency. In the presence of anosmia, idiopathic hypogonadotropic hypogonadism has been called 'Kallmann syndrome (KS),' whereas in the presence of a normal sense of smell, it has been termed 'normosmic idiopathic hypogonadotropic hypogonadism (nIHH)' (Raivio et al., 2007).

APRT	Adenine phosphoribosyltransferase deficiency Adenine phosphoribosyltransferase deficiency Descrição da doença: Adenine phosphoribosyltransferase deficiency is an autosomal recessive metabolic disorder that can lead to accumulation of the insoluble purine 2,8-dihydroxyadenine (DHA) in the kidney, which results in crystalluria and the formation of urinary stones. Clinical features include renal colic, hematuria, urinary tract infection, dysuria, and, in some cases, renal failure. The age at onset can range from 5 months to late adulthood; however, as many as 50% of APRT-deficient individuals may be asymptomatic (Sahota et al., 2001).Two types of APRT deficiency have been described based on the level of residual enzyme activity in in vitro studies of erythrocytes. Type I deficiency is characterized by complete enzyme deficiency in intact cells and in cell lysates, whereas type II deficiency is characterized by complete enzyme deficiency in intact cells, but only a partial deficiency in cell lysates. Type II alleles show reduced affinity for phosphoribosyl pyrophosphate (PRPP) compared to wildtype. In both types, APRT activity is not functional in vivo. Type II deficiency is most common among Japanese. Heterozygotes of either type do not appear to have any clinical or biochemical abnormalities (Sahota et al., 2001).

The age at onset can range from 5 months to late adulthood; however, as many as 50% of APRT-deficient individuals may be asymptomatic (Sahota et al., 2001).Two types of APRT deficiency have been described based on the level of residual enzyme activity in in vitro studies of erythrocytes. Type I deficiency is characterized by complete enzyme deficiency in intact cells and in cell lysates, whereas type II deficiency is characterized by complete enzyme deficiency in intact cells, but only a partial deficiency in cell lysates. Type II alleles show reduced affinity for phosphoribosyl pyrophosphate (PRPP) compared to wildtype. In both types, APRT activity is not functional in vivo. Type II deficiency is most common among Japanese. Heterozygotes of either type do not appear to have any clinical or biochemical abnormalities (Sahota et al., 2001).	Plus

Approximately 75% of EIEE patients progress to 'West syndrome,' which is characterized by tonic spasms with clustering, arrest of psychomotor development, and hypsarrhythmia on EEG (Kato et al., 2007). EIEE1 is part of a phenotypic spectrum of disorders caused by mutation in the ARX gene comprising a nearly continuous series of developmental disorders ranging from lissencephaly (LISX2; 300215) to Proud syndrome (300004) to infantile spasms without brain malformations (EIEE1) to syndromic (Partington syndrome; 309510) and nonsyndromic (Mental retardation, X-linked type 29; 300419) mental retardation. Although males with ARX mutations are often more severely affected, female mutation carriers may also be affected (Kato et al., 2004; Wallerstein et al., 2008). The prevalence is <1:1,000,000.

ASAH1	Farber lipogranulomatosis; Spinal muscular atrophy with progressive myoclonic epilepsy Farber lipogranulomatosis; Spinal muscular atrophy with progressive myoclonic epilepsy Descrição da doença: Farber lipogranulomatosis is an autosomal recessive lysosomal storage disorder characterized by early-onset subcutaneous nodules, painful and progressively deformed joints, and hoarseness by laryngeal involvement. Based on the age of onset, the severity of symptoms, and the difference in organs affected, 6 clinical subtypes due to deficiency of acid ceramidase have been distinguished. The most severe form is subtype 4, a rare neonatal form of the disease with death occurring before 1 year of age (Alves et al., 2013). Biallelic mutation in the ASAH1 gene can also cause spinal muscular atrophy with progressive myoclonic epilepsy (SMAPME). Spinal muscular atrophy with progressive myoclonic epilepsy is an autosomal recessive neuromuscular disorder characterized by childhood onset of proximal muscle weakness and generalized muscular atrophy due to degeneration of spinal motor neurons, followed by the onset of myoclonic seizures. The disorder is progressive, and usually results in loss of ambulation and early death from respiratory insufficiency (Zhou et al., 2012).

(AT) is an autosomal recessive disorder characterized by cerebellar ataxia, telangiectases, immune defects, and a predisposition to malignancy. Chromosomal breakage is a feature. AT cells are abnormally sensitive to killing by ionizing radiation (IR), and abnormally resistant to inhibition of DNA synthesis by ionizing radiation. The latter trait has been used to identify complementation groups for the classic form of the disease (Jaspers et al., 1988). At least 4 of these (A, C, D, and E) map to chromosome 11q23 (Sanal et al., 1990) and are associated with mutations in the ATM gene.	Plus
ATOH7	Persistent hyperplastic primary vitreous, autosomal recessive Persistent hyperplastic primary vitreous, autosomal recessive Descrição da doença: Persistent hyperplastic primary vitreous (PHPV), also termed 'persistent fetal vasculature,' is a developmental malformation of the eye in which the primary vitreous fails to regress in utero, resulting in the presence of a retrolental fibrovascular membrane with persistence of the posterior portion of the tunica vasculosa lentis and hyaloid artery. This abnormality is usually unilateral and associated with microphthalmia, cataract, glaucoma, and congenital retinal nonattachment (Haddad et al., 1978; Khaliq et al., 2001; Prasov et al., 2012).PHPV shares phenotypic overlap with Norrie disease (310600).

ATP13A2	Kufor-Rakeb syndrome; Spastic paraplegia, type 78, autosomal recessive Kufor-Rakeb syndrome; Spastic paraplegia, type 78, autosomal recessive Descrição da doença: Kufor-Rakeb syndrome is a rare autosomal recessive form of juvenile-onset atypical Parkinson disease (PARK9) associated with supranuclear gaze palsy, spasticity, and dementia. Some patients have neuroradiologic evidence of iron deposition in the basal ganglia, indicating that the pathogenesis of PARK9 can be considered among the syndromes of neurodegeneration with brain iron accumulation (NBIA; 234200) (Bruggemann et al., 2010). Biallelic mutation in the ATP13A2 gene also causes autosomal recessive spastic paraplegia, type 78, an adult-onset neurodegenerative disorder with overlapping features. Patients with SPG78 have later onset and prominent spasticity, but rarely parkinsonism. Loss of ATP13A2 function results in a multidimensional spectrum of neurologic features reflecting various regions of the brain and nervous system, including cortical, pyramidal, extrapyramidal, brainstem, cerebellar, and peripheral (Estrada-Cuzcano et al., 2017).

ATP6V0A2	Cutis laxa, autosomal recessive, type 2A; Wrinkly skin syndrome Cutis laxa, autosomal recessive, type 2A; Wrinkly skin syndrome Descrição da doença: Autosomal recessive cutis laxa type 2 (ARCL2) represents a spectrum of clinical entities with variable severity of cutis laxa, abnormal growth, developmental delay, and associated skeletal abnormalities. Aside from cutis laxa, persistent wide fontanels, frontal bossing, slight oxycephaly, downward-slanted palpebral fissures, reversed-V eyebrows, and dental caries are characteristic. Patients with ARCL2 can be divided into 2 major groups: ARCL2A, comprising those with a combined N- and O-linked glycosylation defect (CDG type 2), and ARCL2B, those without a metabolic disorder (Morava et al., 2009). Van Maldergem et al. (2008) concluded that ARCL2A should be considered more of a multisystem disorder with cobblestone-like brain dysgenesis manifesting as developmental delay and an epileptic neurodegenerative syndrome rather than purely a dermatologic disorder. Mutation in the ATP6V0A2 gen can also cause wrinkly skin syndrome (WWS). WSS is characterized by wrinkling of the skin of the dorsum of the hands and feet, an increased number of palmar and plantar creases, wrinkled abdominal skin, multiple skeletal abnormalities (joint laxity and congenital hip dislocation), late closing of the anterior fontanel, microcephaly, pre- and postnatal growth retardation, developmental delay and facial dysmorphism (a broad nasal bridge, downslanting palpebral fissures and hypertelorism). The occurrence of mutations in the same gene in WSS indicates that ARCL2 and some cases of WSS represent variable manifestations of the same genetic defect.

ATP7A	Menkes disease; Occipital horn syndrome Menkes disease; Occipital horn syndrome Descrição da doença: Menkes disease follows an X-linked pattern of inheritance and is caused by pathogenic variants in the ATP7A gene located on chromosomal region Xq21.1. The age of onset is neonatal/infantile. This disease is characterized by progressive neurodegeneration and marked connective tissue anomalies as well as typical sparse abnormal steely hair. The birth incidence is 1:300,000 in Europe, 1:360,000 in Japan and 1:50,000-1:100,000 in Australia, and the prevalence is 1:100,000 newborns. Mutations in the ATP7A can also cause occipital horn syndrome, which is considered a mild form of Menkes syndrome. Occipital horn syndrome is a rare connective tissue disorder characterized by hyperelastic and bruisable skin, hernias, bladder diverticula, hyperextensible joints, varicosities, and multiple skeletal abnormalities.

AVPR2	Diabetes insipidus, nephrogenic, type 1; Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) Diabetes insipidus, nephrogenic, type 1; Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) Descrição da doença: Nephrogenic diabetes insipidus (NDI) is caused by the inability of the renal collecting ducts to absorb water in response to antidiuretic hormone (ADH), also known as arginine vasopression (AVP; 192340). Approximately 90% of patients are males with the X-linked recessive form (type I), which is caused by a defect in the vasopressin V2 receptor in renal collecting duct cells. The remaining 10% of patients have autosomal NDI (125800) (type II), which is caused by mutations in the gene encoding the aquaporin-2 water channel (AQP2; 107777) on chromosome 12q13 (Morello and Bichet, 2001).Neurogenic, or central, diabetes insipidus (125700) is caused by mutation in the gene encoding arginine vasopression, located on 20p13. Gain-of-function mutations in the AVPR2 gene result in nephrogenic syndrome of inappropriate antidiuresis (NSIAD). The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a common cause of hyponatremia. The syndrome manifests as an inability to excrete a free water load, with inappropriately concentrated urine and resultant hyponatremia, hypoosmolality, and natriuresis. SIADH occurs in a setting of normal blood volume, without evidence of renal disease or deficiency of thyroxine or cortisol. Although usually transient, SIADH may be chronic; it is often associated with drug use or a lesion in the central nervous system or lung. When the cardinal features of SIADH were defined by Bartter and Schwartz (1967), levels of AVP could not be measured. Subsequently, radioimmunoassays revealed that SIADH is usually associated with measurably elevated serum levels of AVP. Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) is characterized by a clinical picture similar to SIADH, but is associated with undetectable levels of AVP (Feldman et al., 2005).

C3	Complement component 3 deficiency Complement component 3 deficiency Descrição da doença: C3 deficiency follows an autosomal recessive pattern of inheritance and is caused by pathogenic variants in the C3 gene located on chromosomal region 19p13.3-p13.2. The age of onset is infantile. It is a rare defect of the complement classical pathway. The main clinical manifestation of primary C3 deficiency is childhood-onset of recurrent bacterial infections, mainly caused by gram-negative bacteria, such as Neisseria meningitidis, Enterobacter aerogenes, Haemophilus influenzae, and Escherichia coli; infections with gram-positive bacteria also occur. Infections in the upper and lower respiratory tract, including pneumonia, episodes of sinusitis, tonsillitis, and otitis, are the most frequent consequence of the C3 deficiency. Approximately 26% of patients with C3 deficiency develop immune complex-mediated autoimmune diseases resembling systemic lupus erythematosus, and about 26% of patients develop mesangiocapillary or membranoproliferative glomerulonephritis, resulting in renal failure (summary by Reis et al., 2006).

C8orf37	Bardet-Biedl syndrome, type 21; Cone-rod dystrophy 16 and Retintis pigmentosa 64 Bardet-Biedl syndrome, type 21; Cone-rod dystrophy 16 and Retintis pigmentosa 64 Descrição da doença: Bardet-Biedl syndrome 21 (BBS21) is an autosomal recessive ciliopathy characterized by obesity, postaxial polydactyly, retinal degeneration, and mild cognitive impairment (Heon et al., 2016; Khan et al., 2016). Mutation in the C8ORF37 gene can also cause cone-rod dystrophy (CORD16) and isolated retinitis pigmentosa (RP64). CORD16 and RP64 are clinically and genetically overlapping heterogeneous retinal dystrophies. RP is characterized initially by rod photoreceptor dysfunction, giving rise to night blindness, which is followed by progressive rod and cone photoreceptor dystrophy, resulting in midperipheral vision loss, tunnel vision, and sometimes blindness. In contrast to RP, CORD is characterized by a primary loss of cone photoreceptors and subsequent or simultaneous loss of rod photoreceptors. The disease in most cases becomes apparent during primary-school years, and symptoms include photoaversion, decrease in visual acuity with or without nystagmus, color vision defects, and decreased sensitivity of the central visual field. Because rods are also involved, night blindness and peripheral vision loss can occur. The diagnosis of CORD is mainly based on electroretinogram (ERG) recordings, in which cone responses are more severely reduced than, or equally as reduced as rod responses (Estrada-Cuzcano et al., 2012).

Rod impairment may occur at the same time as the cone impairment or appear later. Patients with CORD usually have reduced visual acuity, photophobia, and color vision defects (Huang et al., 2013). Mutation in the CACNA1F gene can also cause Aland Island eye disease (AIED) and X-linked incomplete congenital stationary night blindness (CSNB2A). AIED is an X-linked recessive retinal disease characterized by fundus hypopigmentation, decreased visual acuity, nystagmus, astigmatism, protan color vision defect (303900), progressive myopia, and defective dark adaptation. Although AIED has been referred to as a form of albinism, there is no misrouting of the optic nerves, which excludes it from the formal diagnosis of classic albinism (King et al., 2001). CSNB2A is a nonprogressive retinal disorder characterized by decreased visual acuity and loss of night vision. All affected members of the family mapped by Bergen et al. (1996) to Xp21.1 had myopia and a fine horizontal nystagmus. None of them experienced deterioration, during an average follow-up of 5 years, of their visual acuity or ERG recordings.

CANT1	Desbuquois dysplasia, type 1; Epiphyseal dysplasia, multiple, type 7 Desbuquois dysplasia, type 1; Epiphyseal dysplasia, multiple, type 7 Descrição da doença: Desbuquois dysplasia (DBQD) is an autosomal recessive chondrodysplasia belonging to the multiple dislocation group and characterized by severe prenatal and postnatal growth retardation (stature less than -5 SD), joint laxity, short extremities, and progressive scoliosis. The main radiologic features are short long bones with metaphyseal splay, a 'Swedish key' appearance of the proximal femur (exaggerated trochanter), and advanced carpal and tarsal bone age with a delta phalanx (Huber et al., 2009).Desbuquois dysplasia is clinically and radiographically heterogeneous, and had been classified into 2 types based on the presence (type 1) or absence (type 2) of characteristic hand anomalies, including an extra ossification center distal to the second metacarpal, delta phalanx, bifid distal thumb phalanx, and dislocation of the interphalangeal joints (Faivre et al., 2004). However, patients with and without these additional hand anomalies have been reported to have mutations in the same gene (see, e.g., CANT1); thus, these features are not distinctive criteria to predict the molecular basis of DBQD (Furuichi et al., 2011). In addition, Kim et al. (2010) described another milder variant of DBQD with almost normal outwardly appearing hands, but significant radiographic changes, including short metacarpals, elongated phalanges, and remarkably advanced carpal bone age. However, there is no accessory ossification center distal to the second metacarpal, and patients do not have thumb anomalies. Similar changes occur in the feet. These patients also tend to develop precocious osteoarthritis of the hand and spine with age. This phenotype is sometimes referred to as the 'Kim variant' of DBQD (Furuichi et al., 2011). Other forms of skeletal dysplasia caused by mutation in the CANT1 gene include epiphyseal dysplasia, type 7 (EDM7). EDM7 is a form of multiple epiphyseal dysplasia, a generalized skeletal dysplasia associated with significant morbidity. Joint pain, joint deformity, waddling gait, and short stature are the main clinical signs and symptoms. Radiological examination of the skeleton shows delayed, irregular mineralization of the epiphyseal ossification centers and of the centers of the carpal and tarsal bones. Multiple epiphyseal dysplasia is broadly categorized into the more severe Fairbank and the milder Ribbing types. The Fairbank type is characterized by shortness of stature, short and stubby fingers, small epiphyses in several joints, including the knee, ankle, hand, and hip. The Ribbing type is confined predominantly to the hip joints and is characterized by hands that are normal and stature that is normal or near-normal. EDM7 inheritance is autosomal recessive.

CAPN3	Limb-girdle muscular dystrophy, type 1 (LGMD R1) Limb-girdle muscular dystrophy, type 1 (LGMD R1) Descrição da doença: Limb-girdle muscular dystrophy type 1 (LGMDR1; formerly LGMD2A) follows an autosomal recessive pattern of inheritance and is caused by biallelic pathogenic variants in the CAPN3 gene located on chromosomal region 15q15.1. The age of onset is variable. This disease is characterized by a variable age of onset of progressive, typically symmetrical and selective weakness and atrophy of proximal shoulder- and pelvic-girdle muscles (gluteus maximus, thigh adductors, and muscles of the posterior compartment of the limbs are most commonly affected) without cardiac or facial involvement.

CHRDL1	Megalocornea 1, X-linked Megalocornea 1, X-linked Descrição da doença: Megalocornea is an inherited eye disorder in which the corneal diameter is bilaterally enlarged (greater than 13 mm) without an increase in intraocular pressure. It may also be referred to as 'anterior megalophthalmos,' since the entire anterior segment is larger than normal. Features of megalocornea in addition to a deep anterior chamber include astigmatic refractive errors, atrophy of the iris stroma, miosis secondary to decreased function of the dilator muscle, iridodonesis, and tremulousness, subluxation, or dislocation of the lens. Whereas most affected individuals exhibit normal ocular function, complications include cataract development and glaucoma following lenticular dislocation or subluxation. X-linked recessive inheritance is the most common pattern, accounting for the male preponderance of the disorder (Skuta et al., 1983).Megalocornea sometimes occurs as part of the Marfan syndrome (154700).

CHRND	Myasthenic syndrome, congenital, type 3B, fast-channel; Multiple pterygium syndrome, lethal type Myasthenic syndrome, congenital, type 3B, fast-channel; Multiple pterygium syndrome, lethal type Descrição da doença: Fast-channel congenital myasthenic syndrome (FCCMS) is a disorder of the postsynaptic neuromuscular junction (NMJ) characterized by early-onset progressive muscle weakness. The disorder results from kinetic abnormalities of the acetylcholine receptor channel, specifically from abnormally brief opening and activity of the channel, with a rapid decay in endplate current and a failure to reach the threshold for depolarization. Treatment with pyridostigmine or amifampridine may be helpful; quinine, quinidine, and fluoxetine should be avoided (Sine et al., 2003 and Engel et al., 2015). Mutations in CHRND gene can also caused multiple pterygium syndrome, lethal type (LMPS). LMPS is a multiple pterygia are found infrequently in children with arthrogryposis and in fetuses with fetal akinesia syndrome. In lethal multiple pterygium syndrome there is intrauterine growth retardation, multiple pterygia, and flexion contractures causing severe arthrogryposis and fetal akinesia.

Patients present clinically with onset of variable muscle weakness between infancy and adulthood. These disorders have been classified according to the location of the defect: presynaptic, synaptic, and postsynaptic, as well as by pathologic mechanism and electrophysiologic studies (i.e., acetylcholine receptor (AChR) deficiency, slow-channel or fast-channel kinetic defects at the AChR) ( Engel et al., 2003; Engel et al., 2015).

CHRNG	Multiple pterygium syndrome (MPS), Escobar type; MPS, lethal type Multiple pterygium syndrome (MPS), Escobar type; MPS, lethal type Descrição da doença: Multiple pterygium syndromes (MPS) comprise a group of multiple congenital anomaly disorders characterized by webbing (pterygia) of the neck, elbows, and/or knees and joint contractures (arthrogryposis) (Morgan et al., 2006). The multiple pterygium syndromes are phenotypically and genetically heterogeneous but are traditionally divided into prenatally lethal and nonlethal (Escobar) types. In people with MPS, Escobar type, the webbing typically affects the skin of the neck, fingers, forearms, inner thighs, and backs of the knee. People with this type may also have arthrogryposis. A side-to-side curvature of the spine (scoliosis) is sometimes seen. Affected individuals may also have respiratory distress at birth due to underdeveloped lungs (lung hypoplasia). People with Escobar type usually have distinctive facial features including droopy eyelids (ptosis), outside corners of the eyes that point downward (downslanting palpebral fissures), skin folds covering the inner corner of the eyes (epicanthal folds), a small jaw, and low-set ears. Males with this condition can have undescended testes (cryptorchidism). This condition does not worsen after birth, and affected individuals typically do not have muscle weakness later in life. Lethal MPS has many of the same signs and symptoms as the Escobar type. In addition, affected fetuses may develop a buildup of excess fluid in the body (hydrops fetalis) or a fluid-filled sac typically found on the back of the neck (cystic hygroma). Individuals with this type have severe arthrogryposis. Lethal type is associated with abnormalities such as underdevelopment (hypoplasia) of the heart, lung, or brain; twisting of the intestines (intestinal malrotation); kidney abnormalities; an opening in the roof of the mouth (a cleft palate); and an unusually small head size (microcephaly). Affected individuals may also develop a hole in the muscle that separates the abdomen from the chest cavity (the diaphragm), a condition called a congenital diaphragmatic hernia. Lethal multiple pterygium syndrome is typically fatal in the second or third trimester of pregnancy.

In addition, affected fetuses may develop a buildup of excess fluid in the body (hydrops fetalis) or a fluid-filled sac typically found on the back of the neck (cystic hygroma). Individuals with this type have severe arthrogryposis. Lethal type is associated with abnormalities such as underdevelopment (hypoplasia) of the heart, lung, or brain; twisting of the intestines (intestinal malrotation); kidney abnormalities; an opening in the roof of the mouth (a cleft palate); and an unusually small head size (microcephaly). Affected individuals may also develop a hole in the muscle that separates the abdomen from the chest cavity (the diaphragm), a condition called a congenital diaphragmatic hernia. Lethal multiple pterygium syndrome is typically fatal in the second or third trimester of pregnancy.	Plus
CHST14	Ehlers-Danlos syndrome, musculocontractural, type 1 Ehlers-Danlos syndrome, musculocontractural, type 1 Descrição da doença: The Ehlers-Danlos syndromes (EDS) are a group of heritable connective tissue disorders that share the common features of skin hyperextensibility, articular hypermobility, and tissue fragility (Beighton et al., 1998).The major characteristics of the musculocontractural form of EDS include distinctive craniofacial dysmorphism, congenital contractures of thumbs and fingers, clubfeet, severe kyphoscoliosis, muscular hypotonia, hyperextensible thin skin with easy bruisability and atrophic scarring, wrinkled palms, joint hypermobility, and ocular involvement (Malfait et al., 2010). Janecke et al. (2015) reviewed the clinical findings in 34 reported EDSMC patients, 31 with CHST14 mutations and 3 with DSE (605942) mutations (615539), and stated that the disorder can be recognized based on the presence of distal arthrogryposis, including adducted thumbs or clenched fists and talipes equinovarus, as well as hands with atypically shallow palmar creases and tapering fingers, and neonatal muscular hypotonia. Characteristic craniofacial features include brachycephaly, large fontanel, hypertelorism, downslanting palpebral fissures, microcorneae, strabismus, prominent nasolabial folds, short philtrum, thin upper lip, small mouth, high palate, microretrognathia, and prominent and often low-set and posteriorly rotated ears. In addition, EDSMC patients show muscular hypoplasia and weakness, which has been confirmed by ultrasound and electromyography, and intellectual development appears to be normal.

CHST3	Spondyloepiphyseal dysplasia with congenital joint dislocations Spondyloepiphyseal dysplasia with congenital joint dislocations Descrição da doença: Although patients with mutations in the CHST3 gene may initially be given varying diagnostic labels, they have similar clinical features, including dislocation of the knees and/or hips at birth, clubfoot, elbow joint dysplasia with subluxation and limited extension, short stature, and progressive kyphosis developing in late childhood. The disorder is usually evident at birth, with short stature and multiple joint dislocations or subluxations that dominate the neonatal clinical and radiographic picture, and affected individuals may receive an initial clinical diagnosis of Larsen syndrome (245600) or humerospinal dysostosis. During childhood, the dislocations improve, both spontaneously and with surgical treatment, and features of spondyloepiphyseal dysplasia become apparent, leading to arthritis of the hips and spine with intervertebral disc degeneration, rigid kyphoscoliosis, and trunk shortening by late childhood; at this stage, the clinical features are those previously described as the Omani type of SED (Unger et al., 2010).

CIITA	Bare lymphocyte syndrome, type 2, complementation group A Bare lymphocyte syndrome, type 2, complementation group A Descrição da doença: Bare lymphocyte syndrome type 2 (BLS II) is an inherited disorder of the immune system categorized as a form of combined immunodeficiency (CID). People with BLS II lack virtually all immune protection from bacteria, viruses, and fungi. They are prone to repeated and persistent infections that can be very serious or life-threatening. These infections are often caused by "opportunistic" organisms that ordinarily do not cause illness in people with a normal immune system. BLS 2 is typically diagnosed in the first year of life. Most affected infants have persistent infections in the respiratory, gastrointestinal, and urinary tracts. Because of the infections, affected infants have difficulty absorbing nutrients (malabsorption), and they grow more slowly than their peers. Eventually, the persistent infections lead to organ failure. Without treatment, individuals with BLS 2 usually do not survive past early childhood.

CLCF1	Cold-induced sweating syndrome 2 Cold-induced sweating syndrome 2 Descrição da doença: Cold-induced sweating syndrome is an autosomal recessive disorder characterized in the neonatal period by orofacial weakness with impaired sucking and swallowing resulting in poor feeding necessitating medical intervention. Affected infants show a tendency to startle, with contractions of the facial muscles in response to tactile stimuli or during crying, trismus, abundant salivation, and opisthotonus. During the first year, most infants have spiking fevers. These features, referred to as 'Crisponi syndrome' in infancy, can result in early death without advanced care. After the first 2 years, the abnormal muscle contractions and fevers abate, and most patients show normal psychomotor development. From childhood onward, the most disabling symptoms stem from impaired thermoregulation and disabling abnormal sweating, which can be treated with clonidine. Patients have hyperhidrosis, mainly of the upper body, in response to cold temperatures, and sweat very little with heat. Other features include characteristic facial anomalies, such as round face, chubby cheeks, micrognathia, high-arched palate, low-set ears, and depressed nasal bridge, dental decay, camptodactyly, and progressive kyphoscoliosis (Hahn et al., 2010).

COX10	Mitochondrial complex IV deficiency; Leigh syndrome due to mitochondrial COX4 deficiency Mitochondrial complex IV deficiency; Leigh syndrome due to mitochondrial COX4 deficiency Descrição da doença: The COX10 gene encodes a cytochrome c oxidase (COX) assembly protein involved in the mitochondrial heme biosynthetic pathway. Mutations in COX10 gene cause differentes phenotypes such as mitochondrial complex IV deficiency and Leigh syndrome. Complex IV (cytochrome c oxidase) is the terminal enzyme of the respiratory chain and consists of 13 polypeptide subunits, 3 of which are encoded by mitochondrial DNA. The 3 mitochondrially encoded proteins in the cytochrome oxidase complex are the actual catalytic subunits that carry out the electron transport function (Saraste, 1983). Shoubridge (2001) provided a comprehensive review of cytochrome c oxidase deficiency and noted that most isolated COX deficiencies are inherited as autosomal recessive disorders caused by mutations in nuclear-encoded genes; mutations in the mtDNA-encoded COX subunit genes are relatively rare. Leigh syndrome is an early-onset progressive neurodegenerative disorder with a characteristic neuropathology consisting of focal, bilateral lesions in one or more areas of the central nervous system, including the brainstem, thalamus, basal ganglia, cerebellum, and spinal cord. The lesions are areas of demyelination, gliosis, necrosis, spongiosis, or capillary proliferation. Clinical symptoms depend on which areas of the central nervous system are involved. The most common underlying cause is a defect in oxidative phosphorylation (Dahl, 1998).Leigh syndrome may be a feature of a deficiency of any of the mitochondrial respiratory chain complexes: complex I deficiency (OMIM 252010), complex II deficiency (OMIM 252011), complex III deficiency (OMIM 124000), complex IV deficiency (cytochrome c oxidase; OMIM 220110), or complex V deficiency (OMIM 604273) (summary by Lake et al., 2015).

COX15	Cardioencephalomyopathy, fatal infantile, due to cytochrome c oxidase deficiency, type 2; Leigh syndrome due to cytochrome c oxidase deficiency Cardioencephalomyopathy, fatal infantile, due to cytochrome c oxidase deficiency, type 2; Leigh syndrome due to cytochrome c oxidase deficiency Descrição da doença: Cytochrome c oxidase (COX), the terminal component of the mitochondrial respiratory chain, is a multiheteromeric enzyme embedded in the mitochondrial inner membrane. Mutations in COX gene cause different phenotypes susch as cardioencephalomyopathy and Leigh syndrome. Cardioencephalomyopathy due to cytochrome c oxidase deficiency is an autosomal recessive mitochondrial disorder characterized by onset of cardiomyopathy either in utero or in the first days of life. Most patients also show neurologic abnormalities, such as abnormal breathing pattern, nystagmus, and gyral abnormalities, consistent with encephalopathy. The disorder is usually fatal in early infancy (Papadopoulou et al., 1999). Leigh syndrome is a clinically and genetically heterogeneous disorder resulting from defective mitochondrial energy generation. It most commonly presents as a progressive and severe neurodegenerative disorder with onset within the first months or years of life, and may result in early death. Affected individuals usually show global developmental delay or developmental regression, hypotonia, ataxia, dystonia, and ophthalmologic abnormalities, such as nystagmus or optic atrophy. The neurologic features are associated with the classic findings of T2-weighted hyperintensities in the basal ganglia and/or brainstem on brain imaging. Leigh syndrome can also have detrimental multisystemic affects on the cardiac, hepatic, gastrointestinal, and renal organs. Biochemical studies in patients with Leigh syndrome tend to show increased lactate and abnormalities of mitochondrial oxidative phosphorylation. Thus, Leigh syndrome may be a clinical feature of a primary deficiency of any of the mitochondrial respiratory chain complexes: complex I deficiency (OMIM 252010), complex II deficiency (OMIM 252011), complex III deficiency (OMIM 124000), complex IV deficiency (cytochrome c oxidase; OMIM 220110), or complex V deficiency (OMIM 604273) (summary by Lake et al., 2015).

CTC1	Cerebroretinal microangiopathy with calcifications and cysts Cerebroretinal microangiopathy with calcifications and cysts Descrição da doença: Cerebroretinal microangiopathy with calcifications and cysts (CRMCC), also known as Coats plus syndrome, is an autosomal recessive pleomorphic disorder characterized primarily by intracranial calcifications, leukodystrophy, and brain cysts, resulting in spasticity, ataxia, dystonia, seizures, and cognitive decline. Patients also have retinal telangiectasia and exudates (Coats disease) as well as extraneurologic manifestations, including osteopenia with poor bone healing and a high risk of gastrointestinal bleeding and portal hypertension caused by vasculature ectasias in the stomach, small intestine, and liver. Some individuals also have hair, skin, and nail changes, as well as anemia and thrombocytopenia (Anderson et al., 2012; Polvi et al., 2012).

CYP11B1	Adrenal hyperplasia, congenital, due to 11-beta-hydroxylase deficiency Adrenal hyperplasia, congenital, due to 11-beta-hydroxylase deficiency Descrição da doença: Adrenal hyperplasia, congenital, due to 11-beta-hydroxylase deficiency is an autosomal recessive disorder of corticosteroid biosynthesis resulting in androgen excess, virilization, and hypertension. The defect causes decreased synthesis of cortisol and corticosterone in the zona fasciculata of the adrenal gland, resulting in accumulation of the precursors 11-deoxycortisol and 11-deoxycorticosterone; the latter is a potent salt-retaining mineralocorticoid that leads to arterial hypertension (White et al., 1991).CAH due to 11-beta-hydroxylase deficiency accounts for approximately 5 to 8% of all CAH cases; approximately 90% of cases are caused by 21-hydroxylase deficiency (201910) (White et al., 1991).

CYP11B2	Hypoaldosteronism, congenital, due to CMO I deficiency Hypoaldosteronism, congenital, due to CMO I deficiency Descrição da doença: CMO type I deficiency is an autosomal recessive disorder caused by a defect in the penultimate biochemical step of aldosterone biosynthesis, the 18-hydroxylation of corticosterone (B) to 18-hydroxycorticosterone (18-OHB). This enzymatic defect results in decreased aldosterone and salt-wasting. In CMO I deficiency, aldosterone is undetectable, whereas its immediate precursor, 18-OHB, is low or normal. These patients have an increased ratio of corticosterone to 18-OHB (Portrat-Doyen et al., 1998).The CYP11B2 gene product also catalyzes the final step in aldosterone biosynthesis: the 18-oxidation of 18-OHB to aldosterone. A defect in that enzymatic step results in CMO type II deficiency (610600), an allelic disorder with an overlapping phenotype but distinct biochemical features. In CMO II deficiency, aldosterone can be low or normal, but at the expense of increased secretion of 18-OHB. These patients have a low ratio of corticosterone to 18-OHB (Portrat-Doyen et al., 1998).

CYP19A1	Aromatase deficiency Aromatase deficiency Descrição da doença: Aromatase deficiency is a rare autosomal recessive disorder in which individuals cannot synthesize endogenous estrogens. If a fetus lacks aromatase activity, dehydroepiandrosterone sulfate produced by the fetal adrenal glands cannot be converted to estrogen by the placenta, and is converted to testosterone peripherally and results in virilization of both fetus and mother. Virilization manifests as pseudohermaphroditism in female infants, with hirsutism and acne in the mother; the maternal indicators resolve following delivery. Affected females are usually diagnosed at birth because of the pseudohermaphroditism. Cystic ovaries and delayed bone maturation can occur during childhood and adolescence in these girls, who present at puberty with primary amenorrhea, failure of breast development, virilization, and hypergonadotropic hypogonadism. Affected males do not present with obvious defects at birth. Their clinical symptoms include tall stature, delayed skeletal maturation, delayed epiphyseal closure, bone pain, eunuchoid body proportions, and excess adiposity. Estrogen replacement therapy reverses the symptoms in males and females.

CYP21A2	Congenital adrenal hyperplasia due to 21-hydroxylase deficiency Congenital adrenal hyperplasia due to 21-hydroxylase deficiency Descrição da doença: Classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency follows an autosomal recessive pattern of inheritance and is caused by pathogenic variants in the CYP21A2 gene located on chromosomal region 6p21.3. The age of onset is neonatal/infantile. This disease is characterized by simple virilizing or salt wasting forms that can manifest with genital ambiguity in females, and in both sexes with adrenal insufficiency with dehydration during the neonatal period, life threatening hypoglycemia and hyperandrogenia. The prevalence is 1/100,000 to 9/100,000. There is a common milder form of congenital adrenal hyperplasia (Nonclassic) characterized by a later onset of androgen excess symptoms seen in females and precocious pseudopuberty in both sexes. Cortisol and aldosterone levels are normal but there is an increased amount of androgens. Nonclassic form onset occurs in adolescence with variable degrees of postnatal androgen excess (precocious pubarche, hirsutism, acne, alopecia, anovulation and menstrual irregularies and in the post-pubertal period it can mimic polycystic ovary syndrome. It is also sometimes asymptomatic. The prevalence ranges from 1/1,000-1/500 in the general Caucasian population, but up to 1-2% among inbred populations, such as Eastern European (Ashkenazi) Jews.

Large deposits of cholesterol and cholestanol are found in virtually every tissue, particularly the Achilles tendons, brain, and lungs. Cholestanol, the 5-alpha-dihydro derivative of cholesterol, is enriched relative to cholesterol in all tissues. The diagnosis can be made by demonstrating cholestanol in abnormal amounts in the serum and tendon of persons suspected of being affected. Plasma cholesterol concentrations are low normal in CTX patients. Dotti et al. (2001) examined the ophthalmologic findings of 13 CTX patients. In addition to cataracts, which were found in all cases, optic disc pallor was identified in 6 of the patients. Premature retinal senescence was also observed.In a tabular presentation, Moghadasian et al.

CYP27B1	Vitamin D-dependent rickets, type 1 Vitamin D-dependent rickets, type 1 Descrição da doença: Vitamin D3 (cholecalciferol), synthesized in the epidermis in response to UV radiation, and dietary vitamin D2 (ergocalciferol, synthesized in plants) are devoid of any biologic activity. Vitamin D hormonal activity is due primarily to the hydroxylated metabolite of vitamin D3, 1-alpha,25-dihydroxyvitamin D3 (calcitriol), the actions of which are mediated by the vitamin D receptor (VDR; 601769) (Koren, 2006; Liberman and Marx, 2001).In the liver, vitamin D 25-hydroxylase (CYP2R1; 608713) catalyzes the initial hydroxylation of vitamin D at carbon 25; in the kidney, 1-alpha-hydroxylase (CYP27B1; 609506) catalyzes the hydroxylation and metabolic activation of 25-hydroxyvitamin D3 into 1,25-dihydroxyvitamin D3. The active metabolite 1,25(OH)2D3 binds and activates the nuclear vitamin D receptor, with subsequent regulation of physiologic events such as calcium homeostasis and cellular differentiation and proliferation (Takeyama et al., 1997). Disorders of vitamin D metabolism or action lead to defective bone mineralization and clinical features including intestinal malabsorption of calcium, hypocalcemia, secondary hyperparathyroidism, increased renal clearance of phosphorus, and hypophosphatemia. The combination of hypocalcemia and hypophosphatemia causes impaired mineralization of bone that results in rickets and osteomalacia (Liberman and Marx, 2001).

CYP4F22	Ichthyosis, congenital, autosomal recessive, type 5 Ichthyosis, congenital, autosomal recessive, type 5 Descrição da doença: Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of disorders of keratinization characterized primarily by abnormal skin scaling over the whole body. These disorders are limited to skin, with approximately two-thirds of patients presenting severe symptoms. The main skin phenotypes are lamellar ichthyosis (LI) and nonbullous congenital ichthyosiform erythroderma (NCIE), although phenotypic overlap within the same patient or among patients from the same family can occur (Fischer, 2009). Neither histopathologic findings nor ultrastructural features clearly distinguish between NCIE and LI. In addition, mutations in several genes have been shown to cause both lamellar and nonbullous ichthyosiform erythrodermal phenotypes (Akiyama et al., 2003). At the First Ichthyosis Consensus Conference in Soreze in 2009, the term 'autosomal recessive congenital ichthyosis' (ARCI) was designated to encompass LI, NCIE, and harlequin ichthyosis (ARCI4B; 242500) (Oji et al., 2010).NCIE is characterized by prominent erythroderma and fine white, superficial, semiadherent scales. Most patients present with collodion membrane at birth and have palmoplantar keratoderma, often with painful fissures, digital contractures, and loss of pulp volume. In half of the cases, a nail dystrophy including ridging, subungual hyperkeratosis, or hypoplasia has been described. Ectropion, eclabium, scalp involvement, and loss of eyebrows and lashes seem to be more frequent in NCIE than in lamellar ichthyosis (Fischer et al., 2000). In LI, the scales are large, adherent, dark, and pigmented with no skin erythema. Overlapping phenotypes may depend on the age of the patient and the region of the body. The terminal differentiation of the epidermis is perturbed in both forms, leading to a reduced barrier function and defects of lipid composition in the stratum corneum (Lefevre et al., 2006).In later life, the skin in ARCI may have scales that cover the entire body surface, including the flexural folds, and the scales are highly variable in size and color. Erythema may be very mild and almost invisible. Some affected persons exhibit scarring alopecia, and many have secondary anhidrosis (Eckl et al., 2005).

Perlman syndrome is associated with a high risk of Wilms tumor, with a 64% incidence in infants surviving beyond the neonatal period. The tumor is diagnosed at an earlier age in these individuals compared with sporadic cases (less than 2 years and 3-4 years of age, respectively), and there is a high frequency of bilateral tumors (55%). Histologic examination of the kidneys in children with Perlman syndrome shows frequent nephroblastomatosis, which is a precursor lesion for Wilms tumor (Astuti et al., 2012).
