PharmVar GeneFocus: CYP2C19 [PDF]
The Pharmacogene Variation Consortium (PharmVar) catalogues star (*) allele nomenclature for the polymorphic human CYP2C19 gene. CYP2C19 genetic variation impacts the metabolism of many drugs and has been associated with both efficacy and safety issues for several commonly prescribed medications.

Pharmacogenetics of CYP2C19: functional and clinical implications of a new variant CYP2C19*17 [PDF]
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT • CYP2C19 polymorphisms may have clinical consequences in relation to drugs extensively metabolized by the enzyme.• Recently a new variant CYP2C19*17 was discovered.• Unlike other commonly studied variant alleles, notably CYP2C19*2 and CYP2C19*3, which are defective, CYP2C19*17 is associated with enhanced ...

The influence of the CYP2C19*10 allele on clopidogrel activation and CYP2C19*2 genotyping [PDF]
The polymorphic hepatic enzyme CYP2C19 catalyzes the metabolism of clinically important drugs such as clopidogrel, proton-pump inhibitors, and others and clinical pharmacogenetic testing for clopidogrel is increasingly common. The CYP2C19*10 single-nucleotide polymorphism (SNP) is located 1 bp upstream the CYP2C19*2 SNP.

Pharmacogenomic testing and its future in community pharmacy [PDF]
Although it is common to see pharmacogenomic testing used North America and Australia, it is not yet part of practice in the UK. With the promise of genomic screening becoming part of the NHS, pharmacists must equip themselves with a knowledge of how the

Methodology for clinical genotyping of CYP2D6 and CYP2C19 [PDF]
AbstractMany antidepressants, atomoxetine, and several antipsychotics are metabolized by the cytochrome P450 enzymes CYP2D6 and CYP2C19, and guidelines for prescribers based on genetic variants exist. Although some laboratories offer such testing, there is no consensus regarding validated methodology for clinical genotyping of CYP2D6 and CYP2C19.

CYP2C19 variation and citalopram response [PDF]
Variations in cytochrome P450 (CYP) genes have been shown to be associated with both accelerated and delayed pharmacokinetic clearance of many psychotropic medications. Citalopram is metabolized by three CYP enzymes. CYP2C19 and CYP3A4 play a primary role in citalopram metabolism, whereas CYP2D6 plays a secondary role.The Sequenced Treatment ...

Omeprazole‐induced acute interstitial nephritis is not related to CYP2C19 genotype or CYP2C19 phenotype [PDF]
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT • Omeprazole‐induced acute interstitial nephritis (OIAIN) is a rare adverse drug reaction. It is typically considered to be an idiosyncratic reaction affecting elderly patients. Omeprazole is a substrate for CYP2C19 and individuals who are homozygous variant for the null allele are poor metabolizers of this ...
