What role does VKORC1 play in stress?

VKORC1 encodes the vitamin K epoxide reductase complex subunit 1, a key enzyme in blood coagulation. It recycles vitamin K, which is essential for activating clotting factors. There is no direct evidence linking VKORC1 to stress. However, chronic stress can influence coagulation through increased platelet activity and fibrinogen levels, potentially affecting the vitamin K cycle indirectly. Some mechanistic studies suggest stress may alter vitamin K metabolism, but human data are lacking. The evidence is therefore weak and based on plausible mechanisms rather than clinical trials. VKORC1 variants are primarily studied for warfarin sensitivity, not stress. Thus, a DNA test for VKORC1 is not useful for assessing stress. For stress management, focus on evidence-based approaches like exercise, sleep, and counseling.
