The CYP2C9 gene is highly polymorphic. At least 20 single nucleotide polymorphisms (SNPs) have been reported to have functional evidence of altered enzyme activity. In fact, adverse drug reactions (ADRs) often result from unanticipated changes in CYP2C9 enzyme activity secondary to genetic polymorphisms. Especially for CYP2C9 substrates such as warfarin and phenytoin, diminished metabolic capacity because of genetic polymorphisms or drug-drug interactions can … WebThe CYP2C19 gene is a member of the cytochrome P450 gene family.
