COX7A2 Gene

Cytochrome C Oxidase Subunit 7A2 (COX7A2) is a gene involved in oxidative phosphorylation that has been studied in relation to immune function, metabolism, and chronic illness. Variants in COX7A2 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the COX7A2 gene?

COX7A2 encodes cytochrome c oxidase subunit 7a2, a protein involved in oxidative phosphorylation. It belongs to the Mitochondrial category and is part of the Mitochondrial Energy Production & PEM biological cluster. COX7A2 encodes a subunit of cytochrome c oxidase involved in regulating electron transfer efficiency.

Biological role and pathway

COX7A2 is involved in the oxidative phosphorylation pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. 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 in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

COX7A2 and Long COVID / ME-CFS research

COX7A2 variants may influence mitochondrial respiratory chain efficiency and cellular ATP production relevant to Long COVID fatigue.
