rs12721480

What is the rs12721480 variant?

rs12721480 is a SNP (single nucleotide polymorphism) in the BNIP3 (BCL2 Interacting Protein 3) gene. It belongs to the Mitophagy category and is part of the Mitochondrial Energy Production & PEM biological cluster. BNIP3 encodes a mitophagy receptor induced by hypoxia and BNIP3L/NIX that targets damaged mitochondria for selective autophagy.

Biological role and pathway

This variant sits within the BNIP3 gene, which is involved in the mitophagy / hypoxia response pathway. Genes within the Mitochondrial Energy Production & PEM 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.
