Warfarin pharmacogenomics has been on my mind for quite awhile. Warfarin acts as an anticoagulant by inhibiting the vitamin K cycle which is responsible for creating blood clotting factors. When I learned that vitamin K was produced by bacteria in the gut microbiome, I hypothesized that vitamin K producing capability of the gut microbiome would be associated with warfarin dose requirements.
