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. A component that is no longer current, useful, appropriate or acceptable.
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. Erroneous component (foundation metadata concept)
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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.

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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.

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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.

A group of rare genetic neurodegenerative diseases with characteristics of infancy to childhood onset of progressive spastic paraplegia (with delayed motor milestones, gait disturbances, hyperreflexia and extensor plantar responses), optic atrophy (which may be accompanied by nystagmus and visual loss) and progressive peripheral neuropathy (with sensory impairment and distal muscle weakness/atrophy in upper and lower extremities). Additional signs may include foot deformities, spinal defects (scoliosis, kyphosis), joint contractures, exaggerated startle response, speech disorders, hyperhidrosis, extrapyramidal signs and intellectual disability. In very rare cases, a variant phenotype with less prominent or absent optic atrophy and/or neuropathy may be observed. A component that is no longer current, useful, appropriate or acceptable.
A group of symptoms which may be observed in the fetus or newborn when the mother has taken indomethacin, a nonsteroidal anti-inflammatory drug during pregnancy. The drug crosses the human placenta readily throughout gestation, but its effects on the embryo/fetus vary according to the stage of pregnancy. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.
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 hand-foot malformation with characteristics of triphalangeal thumbs and pre and postaxial polydactyly, isolated syndactyly or complex polysyndactyly. It has been described in some large pedigrees. Clinical presentation is variable within families, ranging from mild to severe. Malformations of the feet are usually less severe than those of the hands. Caused by duplication encompassing the limb-specific regulatory element (ZRS) of sonic hedgehog SHH, which lies in intron 5 of the limb region 1 homolog gene, LMBR1 (7q36). This syndrome is transmitted in an autosomal dominant manner with complete penetrance and variable expression. A component that is no longer current, useful, appropriate or acceptable.
A hearing loss condition that appears as a consequence of annular ligament destruction followed by excessive connective tissue production during the healing process.

A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.
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. A component that is no longer current, useful, appropriate or acceptable.

Other features include slow growth, short stature, skeletal deformities, muscle weakness and bone pain that are associated with normal or elevated plasma levels of calcitriol and hyperphosphaturia. Caused by homozygous or compound heterozygous mutations in the SLC34A3 gene encoding a sodium-dependent phosphate transporter (NaPi-IIc/NPT2c). Transmission is autosomal recessive. A component that is no longer current, useful, appropriate or acceptable.

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. A component that is no longer current, useful, appropriate or acceptable.
