Genes affected

IFNGR1 (HGNC:5439): (interferon gamma receptor 1) This gene (IFNGR1) encodes the ligand-binding chain (alpha) of the gamma interferon receptor. Human interferon-gamma receptor is a heterodimer of IFNGR1 and IFNGR2. A genetic variation in IFNGR1 is associated with susceptibility to Helicobacter pylori infection. In addition, defects in IFNGR1 are a cause of mendelian susceptibility to mycobacterial disease, also known as familial disseminated atypical mycobacterial infection. [provided by RefSeq, Jul 2008]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with IFNGR1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with threonine at codon 477 of the IFNGR1 protein (p.Ile477Thr). The isoleucine residue is highly conserved and there is a moderate physicochemical difference between isoleucine and threonine. -
