GFOD2 (Gfo/Idh/MocA-like oxidoreductase domain containing 2) is an oxidoreductase family member that promotes extracellular matrix assembly and organization [UniProt annotation]. While GFOD2 contains an oxidoreductase domain characteristic of the Gfo/Idh/MocA protein family, its enzymatic activity remains to be conclusively demonstrated 1. GFOD2 shows tissue-specific expression, particularly in the central nervous system where both GFOD family members are expressed during embryonic, larval, and adult developmental stages 2. Functionally, GFOD2 methylation status associates with cumulative stress-weighted life events in psychiatric disorders, with differential methylation at cg03341655 identified in both panic disorder and major depressive disorder cohorts 3. GFOD2 genetic variants modulate metabolic responses, including differential cholesterol lowering responses to dietary interventions and associations with branched-chain amino acid metabolism in insulin resistance and metabolic syndrome 45. Clinically, GFOD2 emerged as a hub gene in sepsis-associated acute lung injury, showing elevated expression and potential responsiveness to therapeutic compounds targeting inflammation, oxidative stress, and tissue remodeling pathways 6. Additionally, GFOD2 methylation patterns are altered following superovulation in reproductive contexts, suggesting sensitivity to hormonal and environmental stressors during oogenesis 7.
