    basic FUNCTION
  • involved in an NADPH-dependent electron transport pathway and oxidizing a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics
  • hydroxylating many xenobiotics inducing phenytoin, S-warfarin, and tolbutamide
  • CYP2C9 and CYP2C19 are important drug-metabolizing enzymes and together metabolize approximately 20 p100 of therapeutically used drugs
  • cytochrome P450 enzyme responsible for metabolizing up to 15 p100 of small molecule drugs
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS electron transport , detoxification

    Susceptibility
  • to adverse drug reactions/toxicities when drugs extensively metabolized by CYP2C9
  • to warfarin resistance
  • to variation of the metabolism of warfarin and other drugs
  • Variant & Polymorphism SNP , other
  • variability interindividual and ethnic
  • increasing the warfarin resistance
  • CYP2C9 variants have significantly decreased function and have the potential to impact the metabolism of warfarin and other drugs
