A rare cutaneous disease and a systemic inherited histiocytosis with main characteristics of hyperpigmentation, hypertrichosis, hepatosplenomegaly, heart anomalies, hearing loss, hypogonadism, low height, and occasionally, hyperglycaemia/diabetes mellitus. The syndrome becomes clinically apparent mostly during childhood, but cases during infancy and late-onset cases have been reported too. Caused by mutations in SLC29A3 (10q22.2) (encoding a nucleoside transporter, hENT3), which result in defective nucleoside transport functions of hENT3. This leads to histiocytic infiltration of numerous organs. Transmission is autosomal recessive.	componente obsoleto (metadato fundacional)

A rare disorder leading to a deficiency of complex I of the respiratory chain with characteristics of neurological dysfunction, hepatic failure and cardiomyopathy. Caused by a mutation in the ACAD9 gene (3q21.3) that encodes the protein ACAD9. This protein has only relatively recently been described but is quite widely expressed in tissues and has activity as an acyl-CoA dehydrogenase with overlapping substrate specificity with very long-chain acyl-CoA dehydrogenase (VLCAD). It also acts an assembly factor for complex I of the respiratory chain and therefore has a vital role in the production of a functioning mitochondrial respiratory chain. The mode of inheritance is autosomal recessive.	componente obsoleto (metadato fundacional)

A rare disorder with characteristics of congenital hypothyroidism, infant respiratory distress syndrome and benign hereditary chorea. Prevalence is unknown but to date about 50 cases have been reported in the literature.The clinical spectrum varies from the complete triad of brain-lung-thyroid syndrome (50%), to brain and thyroid disease (30%), or isolated benign hereditary chorea (13%), which is the mildest expression of the syndrome. In addition, the severity of symptoms varies widely, even in families with the same disease-causing mutation. Brain-lung-thyroid syndrome is caused by mutations in the thyroid transcription factor 1 gene (NKX2-1/TITF1; 14q13.3).	componente obsoleto (metadato fundacional)
A rare disorder with characteristics of neurological problems and neutropenia. Onset of symptoms is in early childhood and severity varies widely among affected individuals. In the most severely affected individuals, features are apparent in infancy and sometimes at birth. Associated with congenital cataracts or cataracts in infancy. The disease is caused by mutations in the CLPB gene which is likely to reduce or eliminate the amount of functional CLPB protein. The severity of the disease may be related to the amount of functional protein that remains. Inherited in an autosomal recessive pattern.	componente obsoleto (metadato fundacional)

A rare disorder with multisystemic involvement and glomerulopathy with characteristics of progressive steroid-resistant nephrotic syndrome typically associated with focal segmental glomerulosclerosis, as well as primary adrenal insufficiency with adrenal calcifications. Age of onset and disease course are variable, with some cases presenting as severe fetal hydrops, while most patients present in infancy or early childhood and progress to end-stage renal disease within a few years. Additional features include ichthyosis, primary hypothyroidism, hypogonadism, immunodeficiency and neurological manifestations (such as cognitive impairment, ataxia, sensorineural hearing loss, or seizures).	componente obsoleto (metadato fundacional)

A rare dysostosis syndrome with characteristics of abnormal fusion of the spleen with the gonad (or more rarely with remnants of the mesonephros), limb abnormalities (consisting of amelia or severe reduction defects leading to upper and/or lower rudimentary limbs) and orofacial abnormalities such as cleft palate, bifid uvula, microglossia and mandibular hypoplasia. It may also be associated with other malformations such as cryptorchidism, anal stenosis/atresia, hypoplastic lungs and cardiac malformations.	componente obsoleto (metadato fundacional)
A rare dysostosis syndrome with characteristics of vertical median craniofacial clefting of fronto-naso-maxillary structures associated with auriculo-mandibular malformations. The syndrome manifests with highly variable craniofacial features which include hypertelorism, eyelid coloboma, orbital dystopia, epibulbar dermoid, nasal anomalies (for example wide nasal bridge, bifid nose, widely separated, slit-like nares, nasal bone dysplasia), auricular and middle ear dysplasia (microtia, aural stenosis, pre-auricular skin tags/pits), cleft lip/palate, mandibular/maxillary hypoplasia and facial asymmetry. Intracranial abnormalities and extra-craniofacial features are frequently associated.	componente obsoleto (metadato fundacional)
A rare dystonia with a combination of hemidystonia involving one half of the body and hemiatrophy on the same side. Hemidystonia which is sustained and repetitive muscle contractions resulting in abnormal movements or posture involving a single side of the body is preceded in 90% of cases by hemiparesis with a marked improvement before the onset of hemidystonia. Pyramidal syndrome and seizures may also be observed. The syndrome is associated with ipsilateral somatic atrophy. Common causes are childbirth or perinatal complications, delayed sequelae of stroke or head trauma. This syndrome should be differentiated from other causes of primary dystonia or dystonia secondary to inherited disorders or neurodegenerative diseases.	componente obsoleto (metadato fundacional)
A rare dystrophic epidermolysis bullosa (DEB) characterised by generalised blistering, milia formation, atrophic scarring, and dystrophic nails. Caused by mutations in the collagen VII gene (COL7A1; 3p21.31) that lead to an alteration of function or a reduction in the amount of collagen VII. The molecular defect impairs collagen VII assembly into anchoring fibrils which fix the basement membrane to the underlying dermis, causing reduced skin resistance to minor trauma. Transmission is autosomal dominant.	componente obsoleto (metadato fundacional)

A rare endocrine disease with characteristics of the triad of adult-onset diabetes mellitus, progressive hearing loss (usually presenting in the first decade of life and principally of low to moderate frequencies), and/or juvenile-onset optic atrophy. Psychiatric (i.e. anxiety, depression, hallucinations) and sleep disorders, the only neurologic abnormalities observed in this disease, have been reported in rare cases. There is evidence this disease is caused by heterozygous mutation in the WFS1 gene on chromosome 4p16.	componente obsoleto (metadato fundacional)
A rare entity usually diagnosed by echocardiography. It may be limited to one of the four valves but can also involve the two atrioventricular valves and the two semilunar valves. May be the hallmark of genetic anomalies. Chromosomal anomalies should be searched when polyvalvular dysplasia is found in a fetus, namely trisomy 18 and trisomy 13. Triscuspid valve dysplasia can be the only cardiac finding in trisomy 21 and a karyotype analysis should be performed in all fetuses exhibiting this anomaly. In the absence of chromosomal anomalies, polyvalvular dysplasia can be observed in Noonan syndrome. Thickening of the different cardiac valves can be observed in various storage diseases such as mucopolysaccharidoses. In these later conditions, it develops after the neonatal period and is frequently associated with extracardiac symptoms suggestive of the diagnosis.	componente obsoleto (metadato fundacional)
