Your CYP2C19 Genetic Test Results and What They Mean

WebFour potential CYP2D6 phenotypic subgroups exist. These groups are usually defined by the respective number of their functional alleles: ultrarapid (3), extensive (2), intermediate (1), and poor metabolizers (0). Most CYP2D6 polymorphisms result in an allele that lacks metabolic activity. 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 ...
