rs41303970

What is the rs41303970 variant?

rs41303970 is a SNP (single nucleotide polymorphism) in the GCLM (Glutamate-Cysteine Ligase Modifier Subunit) gene. It belongs to the Oxidative Stress category and is part of the Oxidative Stress biological cluster. GCLM encodes the regulatory subunit of GCL, which increases the catalytic efficiency of GCLC for glutathione production.

Biological role and pathway

This variant sits within the GCLM gene, which is involved in the glutathione biosynthesis pathway. Genes within the Oxidative Stress 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.
