rs2066807

What is the rs2066807 variant?

rs2066807 is a SNP (single nucleotide polymorphism) in the STAT1 (Signal Transducer and Activator of Transcription 1) gene. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. STAT1 mediates cellular responses to interferons and is central to antiviral gene expression programs.

Biological role and pathway

This variant sits within the STAT1 gene, which is involved in the interferon signaling pathway. Genes within the Immune System & Inflammation cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function — particularly under conditions of physiological stress such as viral infection or prolonged illness.
