rs1050450

What is the rs1050450 variant?

rs1050450 is a SNP (single nucleotide polymorphism) in the GPX1 (Glutathione Peroxidase 1) gene. It belongs to the Oxidative Stress category and is part of the Oxidative Stress biological cluster. GPX1 encodes glutathione peroxidase 1, a selenoprotein enzyme that reduces hydrogen peroxide and lipid hydroperoxides.

Biological role and pathway

This variant sits within the GPX1 gene, which is involved in the antioxidant defense 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.
