rs2665802

What is the rs2665802 variant?

rs2665802 is a SNP (single nucleotide polymorphism) in the GH1 (Growth Hormone 1) gene. It belongs to the Hormonal category and is part of the Hormonal Regulation biological cluster. GH1 encodes growth hormone, a pituitary hormone regulating growth, metabolism, immune function, and tissue repair.

Biological role and pathway

This variant sits within the GH1 gene, which is involved in the somatotropic axis pathway. Genes within the Hormonal Regulation 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.
