rs1293762

What is the rs1293762 variant?

rs1293762 is a SNP (single nucleotide polymorphism) in the OAS2 (2'-5'-Oligoadenylate Synthetase 2) gene. It belongs to the Antiviral category and is part of the Viral Defense & Interferon Response biological cluster. OAS2 encodes a medium-size OAS enzyme that contributes to the antiviral 2-5A/RNase L system.

Biological role and pathway

This variant sits within the OAS2 gene, which is involved in the innate antiviral defense pathway. Genes within the Viral Defense & Interferon Response 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.
