NDUFA9 Gene

What is the NDUFA9 gene?

NDUFA9 encodes nadh:ubiquinone oxidoreductase subunit a9, a protein involved in oxidative phosphorylation Complex I. It belongs to the Mitochondrial category and is part of the Mitochondrial Energy Production & PEM biological cluster. NDUFA9 encodes an accessory subunit of NADH:ubiquinone oxidoreductase (Complex I) involved in its proper assembly and function.

Biological role and pathway

NDUFA9 is involved in the oxidative phosphorylation Complex I 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.

Known genetic variants

The following variants (SNPs) in the NDUFA9 gene have been studied in relation to mitochondrial and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.
