How are VKORC1 and menopause related?

A direct relationship between VKORC1 and menopause is not scientifically established. VKORC1 encodes an enzyme that recycles vitamin K, a cofactor for activating proteins like osteocalcin (bone formation) and matrix Gla protein (vascular protection). During menopause, declining estrogen increases risks for osteoporosis and arterial calcification. Theoretically, VKORC1 variants affecting vitamin K availability could modulate these risks. However, evidence is largely mechanistic; no robust human studies directly link VKORC1 genotypes to menopausal outcomes. Clinically, VKORC1 is primarily used for warfarin dosing. For menopausal women, adequate vitamin K intake (from green leafy vegetables) is advisable regardless of genotype. A genetic test for VKORC1 to predict menopause-related conditions is not evidence-based. The evidence level is therefore 'mechanistic' or 'unclear'.
