rs3212780

What is the rs3212780 variant?

rs3212780 is a SNP (single nucleotide polymorphism) in the JAK3 (Janus Kinase 3) gene. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. JAK3 is a tyrosine kinase required for signaling by common gamma chain cytokines (IL-2, IL-4, IL-7, IL-9, IL-15, IL-21) in lymphocytes.

Biological role and pathway

This variant sits within the JAK3 gene, which is involved in the common gamma chain cytokine 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.
