Alternatively, you may contact the pharmacogenomics pharmacist through the patient portal or through the Children’s Minnesota Pharmacogenomics Program at 612-813-7240. One way to process the medicine is for enzymes (proteins in the body) to change or break down the medicine. CYP2C19 loss-of-function alleles: *2 - *8, CYP2C19 gain-of-funcion allele: *17 Clinical guidelines providing drug prescribing recommendations are listed at PharmGKB: www.pharmgkb.org The PGX-CYP2C19 StripAssay ® allows the discrimination between poor and rapid CYP2C19 metabolizer and in consequence helps to avoid adverse events or failure of therapy. This means that each person has small differences in the genes that code for enzymes. *1/*17), but these individuals are now assigned the CYP2C19 rapid metabolizer phenotype. The part of DNA that instructs how well the CYP2C19 enzyme will work is called the CYP2C19 gene. The assignment of CYP2C19 phenotype is based on the two alleles that the patient carries (also called genotype or diplotype) • There are four CYP2C19 phenotypes — Ultra-rapid metabolizer (UM) — Extensive metabolizer (EM) — Intermediate metabolizer (IM) — Poor metabolizer (PM) Scott SA, et al. Our data indicate that the presence of the CYP2C19*17 allele results in ultra-rapid metabolism of voriconazole after a single oral dose. lizer, intermediate metabolizer, normal metabolizer, rapid metabolizer, and ultrarapid metabolizer), and allele function can be substrate and/or drug concentration dependent. sprechend haben CYP2C19-langsam-Metabolizer ein höheres Nebenwirkungs - risiko, wenn sie die Standarddosis einnehmen.
