Poor metabolizer phenotype
WebMar 5, 2024 · overall GAS, followed by a translation into phenotype categories. Based on the guidelines 4 clinically implemented phenotype categories were assigned: poor metabolizer (PM, GAS = 0.0), intermediate metabolizer (IM, GAS =0.5-1.0), normal metabolizers (NM, GAS=1.5-2.5) and ultra-rapid metabolizers (GAS = 3.0). WebTo date, more than 40 polymorphic variants of CYP2C19 have been identified, and they are related to nearly 35 enzyme isoforms. 10 Allelic variants are associated with defined metabolizer phenotypes. The poor metabolizer (PM) phenotype is characterized by the presence of both alleles, either nonfunctional or null (CYP2C19*2, CYP2C19*3).
