A genetic neurodegenerative disease with normal early development followed by childhood onset optic atrophy with progressive vision loss and eventually blindness, followed by progressive neurological decline that typically includes cerebellar ataxia, nystagmus, dorsal column dysfunction (decreased vibration and position sense), spastic paraplegia and finally tetraparesis. There is evidence this disease is caused by homozygous or compound heterozygous mutation in the UCHL1 gene on chromosome 4p13.	componente obsoleto (metadato fundacional)
A genetic non-syndromic congenital malformation of the neurenteric canal, spinal cord and column characterised by progressive neurologic deterioration (pain, sensorimotor deficits, abnormal gait, decreased tone or abnormal reflexes), musculoskeletal changes (foot deformities and asymmetry, muscle atrophy, limb weakness and numbness, gait disturbances, scoliosis) and/or genitourinary manifestations (bladder and bowel dysfunction). Midline cutaneous stigmata in the lumbosacral region, such as turfs of hair, skin appendages, dimples, subcutaneous lipomas, skin discolouration or haemangiomas, are frequently associated.	componente obsoleto (metadato fundacional)

A genetic transmission deafness syndrome. The profound congenital deafness is associated with a complete absence of inner ear structures (Michel aplasia) microtia type I with small auricle and narrow external auditory canal and microdontia with widely spaced teeth. Linkage analysis followed by sequencing of candidate genes led to identification of three different homozygous mutations in the FGF3 gene (11q13). Transmission is autosomal recessive.	componente obsoleto (metadato fundacional)
A genetic variant of Mendelian susceptibility to mycobacterial disease with characteristics of mild bacillus Calmette-Guérin (BCG) infections and recurrent Salmonella infections. The prevalence is unknown. The disease presents in early childhood. BCG is the most common infection encountered, usually after receiving the vaccination. Non-typhoidal Salmonella infections are also seen in half of all cases. Caused by homozygous mutations in the IL12B gene on chromosome 5q31.1-q33.1 which encodes for the IL-12p40 subunit. There are 9 different IL12B mutant alleles identified, including 2 small insertions, 3 small deletions, 2 splice site mutations, 1 large deletion and 1 nonsense mutation.	componente obsoleto (metadato fundacional)
A genetic variant of Mendelian susceptibility to mycobacterial diseases with characteristics of a complete deficiency in interferon gamma receptor 1(IFN-gammaR1), leading to impaired IFN-gamma immunity and, consequently, to severe and often fatal infections with bacillus Calmette-Guérin and other environmental mycobacteria. Infection is disseminated and can involve soft tissue, bone marrow, lungs, skin, bones and lymph nodes. Manifestations include fever, weight loss, hepatosplenomegaly, lymphadenopathies and lepromatous-like lesions. Caused by complete IFN-gammaR1 deficiency due to mutations in the IFNGR1 gene on chromosome 6q23-q24. Transmission is autosomal recessive.	componente obsoleto (metadato fundacional)
A genetic variant of Mendelian susceptibility to mycobacterial diseases with characteristics of mild bacillus Calmette-Guérin (BCG) infections and recurrent Salmonella infections. The prevalence is unknown. Over 140 cases have been reported in the world. Disease onset usually occurs in patients before the age of 12 with the appearance of BCG disease, usually after receiving the vaccination. Over half of patients with this variant experience an additional infection with non-typhoidal Salmonella. Caused by mutations in the IL12RB1 gene (19p13.1) subunit that encodes for the IL-12R-beta1 chain. These mutations impair the IL-12/IL-23 pathway essential for production of IFN-beta and the resulting immunity against Salmonella and BCG infections. Inherited in an autosomal recessive manner.	componente obsoleto (metadato fundacional)
A genetic variant of Mendelian susceptibly to mycobacterial disease with characteristics of a complete deficiency in interferon gamma receptor 2, leading to an undetectable response to interferon gamma and consequently to severe and often fatal infections with bacillus Calmette-Guérin (BCG) and other environmental mycobacteria. The prevalence is unknown. Only ten children have been identified to date. This disease is caused by mutations in IFNGR2 on chromosome 21q22.1-22.2 which encodes the IFN-gamma receptor signal transducing chain, essential for IFN-gamma mediated immunity. Two clinically indistinguishable forms have been reportedly defined by the presence or absence of protein expression on the cell surface.	componente erróneo (metadato fundacional)
A genetic variant of mendelian susceptibility to mycobacterial disease with characteristics of a partial defect in the interferon (IFN)-gamma pathway, leading to mild mycobacterial infections. The prevalence is unknown. First infections occur after the age of 3. Clinical penetrance is incomplete and some patients are asymptomatic while others have very mild clinical manifestations. Caused by heterozygous mutations in the STAT1 gene on chromosome 2q32.2-q32.3 encoding the signal transducer and activator of transcription 1. Two distinct forms have been described: one affecting phosphorylation and the other impairing DNA-binding activity. Transmission is autosomal dominant.	componente obsoleto (metadato fundacional)
A genetic variant of mendelian susceptibility to mycobacterial disease with characteristics of a partial deficiency leading to impaired IFN-gamma immunity and consequently recurrent moderately severe infections with bacillus Calmette-Guérin (BCG) and other environmental mycobacteria. Caused by heterozygous mutations in the IFNGR1 gene on chromosome 6q23-q24 that encodes the IFN-gamma receptor ligand binding chain. Microdeletion 818del4 is by far the most common mutation and it corresponds to the first documented hotspot for a microdeletion in the human genome. It leads to the expression of IFN-gamma receptor on the cell surface with no signal transduction and therefore patients only show a partial response to IFN-gamma. Transmission is autosomal dominant.	componente obsoleto (metadato fundacional)
A genetic variant of mendelian susceptibility to mycobacterial disease with characteristics of partial deficiency in IFN-gammaR2, leading to impaired response to IFN-gamma and consequently to recurrent moderately severe infections with bacillus Calmette-Guérin (BCG) and other environmental mycobacteria. Caused by a heterozygous mutation in the IFNGR2 gene on chromosome 21q22.1-22.2 that encodes the IFN-gamma receptor ligand binding chain 2. The 186delC mutation corresponds to the first mutation conferring an AD partial IFN-gammaR2 deficiency.	componente obsoleto (metadato fundacional)
A genetic variant of mendelian susceptibility to mycobacterial diseases (MSMD) with characteristics of a partial deficiency in IFN-gammaR1, leading to a residual response to IFN-gamma and, consequently, to recurrent, moderately severe infections with bacillus Calmette-Guérin (BCG) and other environmental mycobacteria. These infections are recurrent but less severe than those seen in MSMD due to complete IFN-gammaR1 and IFN-gammaR2 deficiencies. Caused by homozygous mutations in the IFNGR1 gene on chromosome 6q23-q24 that encodes the IFN-gamma receptor ligand binding chain. The most common mutation is, by far, I87T. This mutation leads to the expression of IFN-gamma receptors on the cell surface with no signal transduction capacity and they therefore only show a partial response to IFN-gamma. Transmission is autosomal recessive.	componente obsoleto (metadato fundacional)
A genetic variant of mendelian susceptibility to mycobacterial diseases (MSMD) with characteristics of a partial deficiency in IFN-gammaR2, leading to a residual response to IFN-gamma and consequently to recurrent, moderately severe infections with bacillus Calmette-Guérin (BCG) and other environmental mycobacteria. Only one patient has been reported with this variant to date. Caused by a homozygous mutation (R114C) in IFNGR2 on chromosome 21q22.1-22.2 that encodes the IFN-gamma receptor ligand binding chain. This mutation leads to a residual cellular response to IFN-gamma in terms of IL12p40 production. Transmission is autosomal recessive.	componente obsoleto (metadato fundacional)
A genetic variant of mendelian susceptibility to mycobacterial diseases characterised by Bacille Calmette-Guerin (BCG) infections. The prevalence is unknown. Caused by mutations in the ISG15 gene (1p36.33), which encodes an IFN-alpha/beta inducible, ubiquitin-like intracellular protein. These mutations impair ISG15 secretion by leucocytes, a molecule which plays an essential role as an IFN-gamma-inducing secreted molecule needed for optimal antimycobacterial immunity. Inherited in an autosomal recessive manner.	componente obsoleto (metadato fundacional)

A glomerular disease with characteristics of severe renal failure and nephrotic syndrome at birth, which rapidly improves in the first weeks of life. The disorder has been described in 15 infants from 5 families originating from Portugal, the Netherlands, Italy, Germany and Morocco. The disease is a congenital disorder where infants present at birth with nephrotic syndrome, acute renal failure (oligoanuria and proteinuria), or both. Respiratory distress and hypertension are also observed during the first days of life. Some degree of dysmorphism may be observed in some cases. Mothers do not show any renal manifestations. Caused by the transplacental transfer of nephritogenic anti-NEP antibodies (IgG1, IgG4 subtypes) from mothers with truncating mutations of the MME gene (3q25.2; coding for NEP), resulting in a functional knockout of MME.	componente obsoleto (metadato fundacional)
A group of anomalies that may result from maternal infection and subsequent fetal infection with the Herpes virus. The virus causes recurrent cutaneous infections in adults, often involving the lips or the genitalia. Herpes infections in other organs, such as the liver or central nervous system, are less frequent. Pregnancy complications including preterm delivery, intrauterine growth retardation, and neonatal infection have been attributed to the Herpes virus. Exposure of the fetus to Herpes virus at the time of delivery carries a serious risk of infection for the newborn.	componente obsoleto (metadato fundacional)

The drug crosses the human placenta readily throughout gestation, but its effects on the embryo/fetus vary according to the stage of pregnancy.	componente obsoleto (metadato fundacional)
A group of tyrosine related oculocutaneous albinism (OCA1) that includes OCA1A, OCA1B, type 1 minimal pigment oculocutaneous albinism (OCA1-MP) and type 1 temperature sensitive oculocutaneous albinism (OCA1-TS). The phenotypic spectrum seen in OCA1 is variable. Pigmentation present in the skin, hair and eyes can range from little or none to pigmentation only to the peripheries. Findings of nystagmus, photophobia and reduced visual acuity are often present. The disease is caused by a mutation in the TYR gene located on chromosome 11q14.3 encoding tyrosinase. Mutations in OCA1A and OCA1B lead to a total or partial loss of the catalytic activity of tyrosinase while those in OCA1-MP and OCA1-TS lead to minimal activity or temperature sensitive tyrosinase proteins. The different forms of OCA1 are all transmitted autosomal recessively.	componente obsoleto (metadato fundacional)
A haematological neoplasm characterised by clonal proliferation of myeloid precursors in the bone marrow, blood and other tissues (spleen, liver), with clinical, morphological and molecular features of myeloproliferative neoplasms (MPN), failing to meet criteria of a specific MPN.

A hereditary disorder associated with impaired DNA double-strand break repair mechanisms with characteristics of microcephaly, unusual facial features, growth and developmental delay, skin anomalies, and pancytopenia, which is associated with combined immunodeficiency. Caused by mutations in the LIG4 gene (13q22-q34). The resulting defect of DNA ligase IV, a component of the classical non-homologous end-joining (NHEJ) pathway, affects the major mechanism of DNA double-strand break repair. Transmission is autosomal recessive.	componente obsoleto (metadato fundacional)
A hereditary neurological disorder with characteristics of excessive startle responses. The disease manifests shortly after birth with violent jerking to noise and touch, and massive and sustained stiffening of the trunk and limbs, clenching fists, and attacks of a high frequency trembling. Motor milestones are often mildly delayed, but intellectual development is usually normal. Mutations in the GLRA1 gene (5q32) are found in about 30% of patients. These mutations are transmitted as an autosomal dominant or recessive trait. The GLRA1 gene encodes the alpha1 subunit of the juvenile neuronal receptor for the inhibitory neurotransmitter, glycine. Mutations of this subunit cause a variety of dysfunctions of the neuronal chloride (Cl-) channel. Mutations in the GLRB, GPHN and SLC6A5 genes (4q31.3, 14q24 and 11p15.2-p15.1) have also been observed.	componente obsoleto (metadato fundacional)
A hereditary neurological disorder with early and severe involvement of both the peripheral and central nervous systems. It has only been described in Finnish families. Some patients show intellectual deficit. Epilepsy is a late manifestation and seizures may be life threatening. Caused by mutations in the C10orf2 gene (10q24) encoding the mitochondrial helicase Twinkle. The c.1523A>G (p.Y508C) causative mutation has been postulated to be a founder mutation. The mutations lead to mtDNA depletion in the brain and the liver but not in the muscle. Inherited in an autosomal recessive manner.	componente obsoleto (metadato fundacional)
A hereditary renal cancer syndrome defined as development of hereditary clear cell renal cell carcinoma (ccRCC) in two or more family members without evidence of constitutional chromosome 3 translocation, von Hippel-Lindau disease or other neoplasm predisposing syndromes associated with ccRCC, such as tuberous sclerosis or Birt-Hogg-Dubbe syndrome.	componente obsoleto (metadato fundacional)

A heterogeneous entity. Its prevalence in the general population is unknown. Nephrotic syndrome has manifestations of marked proteinuria, with reduced plasmatic levels of albumin, and potentially with edema. Familial forms are in most cases related to podocyte protein structural anomalies. Other forms result from a totally different mechanism, which has not yet been elucidated. One of the proposed hypotheses suggests that cells from the immune system could produce one or several circulating factors, which would increase the glomerular permeability to proteins. In some cases, immunosuppressive drugs, in particular cyclosporin, can prove beneficial. However, the progression to end-stage renal failure is frequent. In this case, there is a risk of nephrotic syndrome recurrence after kidney transplant.	componente obsoleto (metadato fundacional)

Transmission is likely autosomal recessive. There have been no further descriptions in the literature since 1984.	componente obsoleto (metadato fundacional)
A lethal skeletal dysplasia with characteristics of cloverleaf skull anomaly, facial dysmorphism, limb shortness, splenic hypo/aplasia and radiological anomalies including thin tubular bones with flared metaphyses and deficient calvarial mineralisation. First described in 1989, less than 30 cases have been reported so far. Aetiology is not well known, but some histological findings report growth plate disorganisation and adjacent diaphyseal ossification. There is evidence that the disease is caused by heterozygous mutation in the FAM111A gene (615292) on chromosome 11q12.	componente obsoleto (metadato fundacional)

A life-threatening disorder, believed to be a cardiovascular clinical variant manifestation of Behcet disease, with the association of multiple pulmonary artery aneurysms and peripheral venous thrombosis. Prevalence is unknown but fewer than 30 cases have been reported in the literature since its first description in 1959 by Hughes and Stovin. Patients (mostly men aged 12-40 years) generally present with the nonspecific signs of pulmonary artery aneurysms, following a history of peripheral venous thrombosis. Other associated signs may include fever and intracranial hypertension. Aneurysms can occur anywhere in the systemic circulation. Recurrent phlebitis also commonly involves the large vessels, resulting in thrombus formation. In general, there is a predisposition for thrombus formation affecting the peripheral veins. It is assumed the disease is a form of vasculitis following a similar mechanism of pathogenesis to that thought to be involved in Behcet disease.	componente obsoleto (metadato fundacional)
A life-threatening multi organ disorder which develops in the first months of life, presenting with respiratory distress and proteinuria in the nephrotic range, and leading to severe interstitial lung disease and renal failure. Some patients additionally display cutaneous alterations, ranging from blistering and skin erosions to an epidermolysis bullosa-like phenotype, with toe nail dystrophy and sparse hair. There is evidence this disease is caused by homozygous mutation in the ITGA3 gene on chromosome 17q21.	componente obsoleto (metadato fundacional)
A life-threatening rapidly progressive thrombotic disorder affecting mainly neonates and children that has characteristics of purpuric skin lesions and disseminated intravascular coagulation. The disease may progress rapidly to multi-organ failure caused by thrombotic occlusion of small and medium-sized blood vessels.

A lysosomal storage disease belonging to the group of sphingolipidoses. It is very rare with less than 10 cases reported in the literature so far. Clinically, it is a severe neurovisceral disease manifesting immediately after birth and following a rapidly progressive fatal course. The neurological signs and symptoms include hypotonia, massive myoclonic bursts, abnormal ocular movements and dystonia. Grand mal seizures and seizures triggered by tactile stimuli have been described. Patients also develop hepatosplenomegaly. Death usually occurs from respiratory failure following repeated pulmonary infections. The disease is caused by mutations in the PSAP gene (10q21) leading to absence or non-functionality of the prosaposin protein. The mode of inheritance is autosomal recessive.	componente obsoleto (metadato fundacional)

A lysosomal storage disease with clinical characteristics of psychomotor retardation and visual abnormalities including corneal clouding, retinal degeneration or strabismus. The disease is rare in the general population but is more prevalent among Ashkenazi Jews. First signs appear during the first year of life or later, but clinical progression is usually slow. In this disease phospholipids, gangliosides and mucopolysaccharides accumulate in lysosomal inclusions, some of which resemble membranous cytoplasmic bodies found in gangliosidoses. The condition seems to be caused by anomalies in the endocytosis of membrane components towards the lysosomes. The causative gene, MCOLN1, is located in the 19p13.3-p13.2 region and encodes mucolipin-1 (MLN1), a membrane protein from the transient receptor potential (TRP) channel family. The disease is transmitted as an autosomal recessive trait.	componente obsoleto (metadato fundacional)
