CYP2C9 is gene 9 within the C subfamily within the 2 family of the CYP450 superfamily. It metabolizes 5% of all prescribed drugs, such as glipizide, phenytoin, and warfarin. Genetic polymorphisms of CYP2C9 could be used to predict the altered enzyme activity and address the potential effects of metabolized drugs. Individuals exhibiting the most common variant alleles of 2C9, *2 or *3 are at increased risk of metabolizing a drug poorly or not at all. Deficient activity of 2C9 may result in reduced or lacking therapeutic benefit and an adverse drug reaction due to metabolite buildup in the body. This should be considered prior to initiating or modifying treatment or supplementing with additional drugs.
