Polymorphisms in genes have been found in most enzymes involved in drug metabolism, especially in the cytochrome P450 (CYP) family with considerable ethnic differences in their frequencies. Single nucleotide polymorphisms (SNPs) are the major source of these genetic variations. CYP2B6 516G>T SNP found in both CYP2B6*6 and CYP2B6*9 alleles significantly reduces CYP2B6 protein expression and enzyme activity with important implications on the pharmacokinetics and pharmacodynamic outcomes of some clinically relevant drug substrates.
