VKORC1

Hematologic System · Coagulation, Fibrin Formation & Fibrinolysis

Why is VKORC1 discussed with vitamin K and warfarin?

VKORC1 makes an enzyme that recycles vitamin K for the activation of clotting proteins. This pathway is relevant to warfarin response, but a genetic finding does not justify independently changing medication or vitamin K intake.

Common Gene Name
vitamin K epoxide reductase complex subunit 1
NCBI Gene ID
79001
Chromosome
16
