rs8050894, is located on chromosome 16 in the gene VKORC1. VKORC1 is the primary target of the drug warfarin (Coumadin), a commonly used oral anticoagulant. rs8050894 is one of several polymorphisms found in VKORC1 that is associated with specific warfarin doses ([PMID 15930419]). Other polymorphisms in VKORC1 (rs7196161, rs9923231, rs9934438, rs2359612) are equally predictive of warfarin dose requirement in both European and Asian-descent individuals.
Other polymorphisms found in the gene cytochrome P450 2C9 (CYP2C9) influence the metabolism of warfarin and have a smaller effect on warfarin dose. These polymorphisms are rs1799853 (CYP2C9*2) and rs1057910 (CYP2C9*3).
[PMID 18841283] In several hundred Europeans, no association was found between rs8050894 and risk for ischemic stroke.
