Genes affected

IFNG (HGNC:5438): (interferon gamma) This gene encodes a soluble cytokine that is a member of the type II interferon class. The encoded protein is secreted by cells of both the innate and adaptive immune systems. The active protein is a homodimer that binds to the interferon gamma receptor which triggers a cellular response to viral and microbial infections. Mutations in this gene are associated with an increased susceptibility to viral, bacterial and parasitic infections and to several autoimmune diseases. [provided by RefSeq, Dec 2015]

Sep 28, 2022

The c.388C>T (p.R130C) alteration is located in exon 4 (coding exon 4) of the IFNG gene. This alteration results from a C to T substitution at nucleotide position 388, causing the arginine (R) at amino acid position 130 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
