How are VKORC1 and sleep related?

The relationship between VKORC1 and sleep is not supported by current scientific evidence. VKORC1 encodes vitamin K epoxide reductase, a key enzyme in the vitamin K cycle, primarily involved in blood coagulation and bone metabolism. It is best known for its role in warfarin sensitivity. No direct link to sleep architecture, circadian rhythms, or sleep quality has been established in the literature. Indirect effects via vitamin K-dependent proteins involved in inflammation or vascular health could theoretically influence sleep regulation, but this remains speculative. The provided knowledge context contains no information connecting VKORC1 to sleep. Therefore, the evidence is unclear. Consumers should be cautious of marketing claims that overstate the role of single genes in complex traits like sleep. Without robust studies, no meaningful conclusion can be drawn.
