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]

Variant summary: IFNGR1 c.1204_1230dup27 (p.Cys402_Asn410dup) results in an in-frame duplication that is predicted to duplicate 9 amino acids into the encoded protein. The variant allele was found at a frequency of 0.00035 in 251006 control chromosomes, predominantly at a frequency of 0.0048 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 4.29 fold of the estimated maximal expected allele frequency for a pathogenic variant in IFNGR1 causing IFN Gamma Receptor Deficiency, Recessive Partial phenotype (0.0011). To our knowledge, no occurrence of c.1204_1230dup27 in individuals affected with IFNGR1-related conditions and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 111209). Based on the evidence outlined above, the variant was classified as likely benign. -
