What to watch with VKORC1 and allergy?

VKORC1 is a key gene for vitamin K metabolism and sensitivity to the anticoagulant warfarin. It has no established direct link to allergies. The association between VKORC1 variants and allergic conditions is not scientifically supported. In nutrigenetic practice, VKORC1 is considered mainly in the context of blood clotting and vitamin K intake, not allergies. If you want to assess allergy predisposition, genes like HLA, FCER1A, or IL-13 are more relevant. The evidence for VKORC1 and allergy is very weak to nonexistent. Be skeptical of commercial tests claiming such a connection – it is not backed by studies.
