SUCLA2 Gene

What is the SUCLA2 gene?

SUCLA2 encodes succinate-coa ligase adp-forming subunit beta, a protein involved in TCA cycle / mitochondrial nucleotide synthesis. It belongs to the Metabolic category and is part of the Mitochondrial Energy Production & PEM biological cluster. SUCLA2 encodes the beta subunit of succinyl-CoA synthetase (ADP-forming), which catalyzes the TCA cycle step from succinyl-CoA to succinate.

Biological role and pathway

SUCLA2 is involved in the TCA cycle / mitochondrial nucleotide synthesis 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 SUCLA2 gene have been studied in relation to metabolic and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.
