rs5748469

What is the rs5748469 variant?

rs5748469 is a SNP (single nucleotide polymorphism) in the TXNRD2 (Thioredoxin Reductase 2) gene. It belongs to the Oxidative Stress category and is part of the Oxidative Stress biological cluster. TXNRD2 encodes the mitochondria-specific thioredoxin reductase that maintains the mitochondrial thioredoxin system.

Biological role and pathway

This variant sits within the TXNRD2 gene, which is involved in the mitochondrial thioredoxin antioxidant system 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.
