Polymorphism affecting drug metabolism
WebThe debrisoquine-sparteine polymorphism of drug oxidation affects the metabolism of more than 40 drugs. The poor metabolizer phenotype is caused by several “loss of function” alleles of the cytochrome P450 CYP2D6 gene. On the other hand, “ultrarapid” metabolizers are caused by duplication or amplification of an active CYP2D6 gene.
