A very rare form of stromal corneal dystrophy with characteristics of irregular amorphous sheet-like opacities in the posterior corneal stroma and in the Descemet membrane along with mildly impaired vision. Prevalence of this form of corneal dystrophy is not known. To date cases have been reported primarily in the USA. Patients usually develop corneal abnormalities in infancy or childhood. The condition is non-progressive or slowly progressive. Unlike other corneal dystrophies, non-corneal manifestations have been observed and include abnormalities of the iris including iridocorneal adhesions, corectopia, and pseudopolycoria. An autosomal dominant pattern of inheritance has been reported.	componente obsoleto (metadato fundacional)
A very rare form of superficial corneal dystrophy with characteristics of feather-shaped opacities and microcysts in the corneal epithelium arranged in a band-shaped and sometimes whorled pattern, occasionally with impaired vision. Exact prevalence of this form of corneal dystrophy is not known but very few cases have been reported to date. Lesions generally develop in childhood. Epithelial opacities are slowly progressive and painless blurred vision sometimes occurs after 60 years of age. The exact cause is unknown but appears to be genetic. The gene related to Lisch epithelial corneal dystrophy has been mapped to the short arm of the X chromosome (Xp22.3).	componente obsoleto (metadato fundacional)
A very rare form of superficial corneal dystrophy with characteristics of frequent recurrent corneal erosions in the first decade of life and progressive loss of vision. The condition has only been reported in one single family. Painful episodes of recurrent corneal erosions occur in the first decade of life but decrease during adolescence. Later in life, patients are reported to develop subepithelial opacities and a corneal haze. The disease eventually progresses over time leading to corneal opacities and loss of vision. The gene related to this disease has not been mapped to a particular chromosomal locus.	componente obsoleto (metadato fundacional)
A very rare genetic bone disorder with characteristics of ankylosis of the proximal interphalangeal joints, carpal and tarsal bone fusion, and conductive hearing loss in some patients.	componente obsoleto (metadato fundacional)
A very rare genetic disorder of water balance, closely resembling the far more frequent syndrome of inappropriate antidiuretic secretion (SIAD) characterised by hypotonic hyponatraemia due to impaired free water excretion and undetectable or low plasma arginine vasopressin (AVP) levels. Symptoms are the classical symptoms of hyponatraemic encephalopathy such as nausea, vomiting, dizziness and gait disturbances. Caused by a gain of function mutation in the type 2 AVP receptor (AVPR2) gene (location Xq28). This mutation leads to constant activation of the AVPR2 receptor on renal collecting duct cells, which causes an increase in free water reabsorption and an increase in urine concentration. An X-linked disorder affecting mainly males with females often being asymptomatic carriers.	componente obsoleto (metadato fundacional)

A very rare genetic vascular disease of autosomal recessive inheritance, described in less than 20 patients to date. The disease has manifestations of adult-onset (as early as the second decade of life) isolated calcification of the arteries of the lower extremities (including the iliac, femoral, and tibial arteries) as well as the capsule joints of the fingers, wrists, ankles and feet.	componente obsoleto (metadato fundacional)
A very rare gonadotropin-independent familial form of male-limited precocious puberty generally presenting between 2-5 years of age as accelerated growth, early development of secondary sexual characteristics and reduced adult height. Caused by an activating mutation of the Lutropin-Choriogonadotropic Hormone Receptor gene (LHCGR, 2p21) which leads to increased levels of sex steroids in the context of low luteinising hormone. This receptor's chronic activation leads to precocious testosterone production by Leydig cells. No effect is observed in female carriers due to the dual luteinising hormone (LH)/ follicle stimulating hormone (FSH) signal necessary to promote ovarian stimulation. Transmission is autosomal dominant. Mothers may act as silent carriers, with each son having a 50% chance of displaying this disorder.	componente obsoleto (metadato fundacional)

A very rare hereditary neurological dysmorphic syndrome with characteristics of moyamoya disease, short stature of postnatal onset and stereotypical facial dysmorphism. The syndrome is extremely rare and has been reported in three unrelated families to date, with 10 affected individuals in several generations. These families are not from Japan or Asia, whereas in general the incidence of moyamoya disease is highest in Japan and other Asian countries, in comparison with other parts of the world. Affected patients are all male (X-linked inheritance) and have moyamoya angiopathy (progressive stenosis of the terminal portion of the intracranial internal carotid arteries), short stature, hypergonadotropic hypogonadism and other variable manifestations.. The genetic cause appears to involve Xq28 deletions removing MTCP1/CMC4 and BRCC3 (Xq28) .The specific pathophysiological mechanisms underlying this disorder remain obscure, but appear to involve alteration in DNA repair.	componente obsoleto (metadato fundacional)
A very rare hereditary skin disease with manifestation of irregularly distributed epidermal hyperkeratosis of the palms and soles. Reported in 35 families worldwide to date. The lesions usually start to develop in early adolescence but can also present later in life. Mutations in the AAGAB gene (15q22.33-q23) have recently been identified as one of the causes. Mutations in the COL14A1 gene (8q23) have also been identified as causal in some cases in Asia that seem to have a similar phenotype	componente obsoleto (metadato fundacional)

A very rare lysosomal storage disease which is the normosomatic form of sialidosis with characteristics of gait abnormalities, progressive visual loss, bilateral macular cherry red spots and myoclonic epilepsy and ataxia, that usually presents in the second to third decade of life. The prevalence is unknown but it is less frequent than sialidosis type 2. This disease is due to a mutation of the N-acetyl-alpha-neuraminidase-1 (NEU1) gene (6p21) encoding the lysosomal enzyme neuraminidase that initiates the degradation of sialoglycoconjugates in lysosomes. Mutations lead to a decrease in enzyme activity and consequently to an accumulation of sialyloligosaccharides in tissues. Disease severity is linked to level of residual neuraminidase activity in vivo and varies between patients. Inherited in an autosomal recessive manner.	componente obsoleto (metadato fundacional)

A very rare subtype of Joubert syndrome and related disorders with characteristics of neurological features of Joubert syndrome associated with orofacial anomalies and often polydactyly. Prevalence is unknown. Typical oral findings include bifid or lobulated tongue, lingual hamartomas and multiple oral frenula, but cleft lip and/or palate can also be present. Two OFD6 patients, including one fetus, were found to carry a homozygous mutation in the TMEM216 gene (11q13.1), but mutations in this gene were excluded in several other patients and the genetic basis of this condition still remains elusive.	componente obsoleto (metadato fundacional)
A very rare subtype of Joubert syndrome with the neurological features of Joubert Syndrome and congenital hepatic fibrosis. Prevalence is unknown. The age of onset and severity of hepatic manifestations are variable. Some patients may also present chorioretinal or optic nerve colobomas and nephronophthisis but these are not mandatory features. Over 70% of cases are due to mutations in the TMEM67 gene (8q22.1).	componente obsoleto (metadato fundacional)
A very rare subtype of autosomal dominant cerebellar ataxia type 3 with characteristics of late-onset and slowly progressive cerebellar signs (gait ataxia) and eye movement abnormalities. To date, only 23 affected patients have been described from one American family of Norwegian descent. Disease onset occurs between the ages of 26-60. A candidate gene has recently been identified as the eukaryotic translation elongation factor 2 (EEF2) gene, located on chromosome 19p13.3. Inherited autosomal dominantly.	componente obsoleto (metadato fundacional)
A very rare subtype of dystrophic epidermolysis bullosa with characteristics of blistering confined primarily to the hands and feet. The disease usually manifests during infancy with trauma-induced blisters limited to extremities. Healing of blisters is associated with milia formation, atrophic scarring and dystrophic nails. There is no extracutaneous involvement. Caused by mutations within the type VII collagen gene (COL7A1). Mutations in this gene lead to an alteration in function of collagen VII. This impairs its assembly into anchoring fibrils that anchor the basement membrane to the underlying dermis. Transmission is autosomal dominant (acral dominant dystrophic epidermolysis bullosa) or autosomal recessive (acral recessive dystrophic epidermolysis bullosa).	componente obsoleto (metadato fundacional)

The reported cases suggest that the condition is hereditary, and is transmitted as an autosomal recessive trait.	componente obsoleto (metadato fundacional)
A very rare syndrome characterised by poorly mineralised calvarium, facial dysmorphism, vertebral abnormalities and absent clavicles. Nine cases have been reported in the literature so far. Dysmorphic features include micrognathia, cleft palate, hypertelorism and upturned nares. Clavicular aplasia is constant and agenesis of cervical vertebral bodies is frequent. Intra uterine growth retardation is constant. It is most likely that the condition is hereditary, transmitted as an autosomal recessive trait. Prognosis is poor, the syndrome is almost always lethal soon after birth.	componente obsoleto (metadato fundacional)
A very rare syndrome characterised by the association of multinodular goitre, cystic renal disease and digital anomalies. It has been described in two siblings and one unrelated child. The two siblings had digitalised thumbs and preaxial polydactyly, the third child had normal thumbs and postaxial polydactyly. Goitre and/or digitalised thumbs and/or polydactyly were present in other members of families. This syndrome seems to be transmitted as an autosomal dominant trait with variable expression and incomplete penetrance.	componente obsoleto (metadato fundacional)
