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: The IFNGR1 c.135C>T (p.Ile45Ile) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. Mutation Taster predicts a benign outcome for this variant. 5/5 splice prediction tools also predict no significant impact on normal splicing. This variant was found in 27/121914 control chromosomes at a frequency of 0.0002215, which does not exceed the estimated maximal expected allele frequency of a pathogenic IFNGR1 variant (0.001118) under recessive module. However, it was found in allele frequency of 4% in 282 randomly selected, population-based individuals 19 to 68 years of age (mean, 38.21) with no atopy-related diseases from Japan (Matsuda_2007); thus it is a polymorphism mainly found in Japanese population. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases. Taken together, this variant is classified as Benign. -
