Myths vs facts: VKORC1 and allergy

VKORC1 is a gene involved in vitamin K recycling and primarily influences sensitivity to anticoagulants like warfarin. There is no scientifically established direct link between VKORC1 variants and allergies. Claims that VKORC1 causes or affects allergies are therefore a myth. The actual relevance lies in blood clotting and individual dosing of anticoagulants. A DNA test for VKORC1 can assist in medication selection but has no proven benefit for allergy diagnosis or prevention. Consumers should be skeptical of marketing that connects VKORC1 with allergies.
