WebWhat does it mean if a patient has poor metabolism phenotype? The poor metabolizer (PM) phenotype occurs when both alleles of either CYP2D6 or CYP2C19 carry inactivating mutations and give rise to synthesis of enzyme with impaired activity or no synthesis of enzyme at all. Spur. WebA correlation has been found between the frequencies of CYP2C19 poor metabolism ‘predicted’ from CYP2C19 genotypes (gPMs) and the poor metabolic phenotype ‘measured’ with a probe drug (mPMs) when subjects are either classified by ethnicity (r=0.94, P<0.001) or geographic region (r=0.99, P=0.002).
