What to watch with VKORC1 and sleep?

VKORC1 is primarily known for its role in vitamin K metabolism and warfarin sensitivity. There is no strong scientific evidence linking VKORC1 variants directly to sleep. If you have a VKORC1 result from a DNA test, it is most relevant for medication dosing (e.g., warfarin), not sleep quality. Sleep is influenced by many other genes (e.g., ADORA2A, CYP1A2, CLOCK) and lifestyle factors. Be cautious of any marketing claims that tie VKORC1 to sleep; they are not supported by current research. If you are taking anticoagulants, follow your doctor's advice, but don't expect VKORC1 to explain insomnia or sleep patterns.
