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]

IFNG-AS1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.
