Functional characterization of the defective CYP2C9 variant CYP2C9*18 [PDF]

Pharmacology Research & Perspectives, 2021
Cytochrome P450 2C9 (CYP2C9) is one of the most important drugs metabolizing enzymes and accounts for the metabolism of about 13%–17% of clinical drugs.

Human CYP2C9 Metabolism of Organophosphorus Pesticides and Nerve Agent Surrogates [PDF]

Journal of Xenobiotics
Of the Cytochrome P450 enzymes, the CYP2C9 variant is very important in the metabolism of several human drugs, acting as a natural bioscavenger. Previously, CYP2C9 was shown to convert the thion (P=S) to the oxon (P=O) form for some organophosphorus (OP)

PharmVar GeneFocus: CYP2C9 [PDF]

Clinical Pharmacology & Therapeutics, 2021
The Pharmacogene Variation Consortium (PharmVar) catalogues star (*) allele nomenclature for the polymorphic human CYP2C9 gene. Genetic variation within the CYP2C9 gene locus impacts the metabolism or bioactivation of many clinically important drugs, including nonsteroidal anti‐inflammatory drugs, phenytoin, antidiabetic agents, and angiotensin ...

Impact of genetic and non-genetic factors on hepatic CYP2C9 expression and activity in Hungarian subjects

Scientific Reports, 2021
CYP2C9, one of the most abundant hepatic cytochrome P450 enzymes, is involved in metabolism of 15–20% of clinically important drugs (warfarin, sulfonylureas, phenytoin, non-steroid anti-inflammatory drugs).

Clinical significance of the series of CYP2C9*non3 variants, an unignorable predictor of warfarin sensitivity in Chinese population

Frontiers in Cardiovascular Medicine, 2022
BackgroundsGene polymorphisms are critical for variations in warfarin dose. To date, more than 70 CYP2C9 alleles have been identified. This study was designed to clarify the clinical significance of CYP2C9*non-3 variants to warfarin sensitivity in ...

Association between CYP2C9 and CYP2C19 Polymorphism, Metabolism, and Neurotoxicity after Administration of Phenytoin: A Systematic Review

Keluwih, 2023
—Phenytoin is an antiepileptic drug (AED) metabolized by cytochrome P450 enzymes, especially by CYP2C9 (90%) and CYP2C19 (10%), where both enzymes are polymorphic so that they can undergo polymorphism and it can change the metabolic rate of the drug ...

Pharmacogenomic implications of the differential distribution of CYP2C9 metabolic phenotypes among Latin American populations

Frontiers in Pharmacology, 2023
The CYP2C9 gene encodes the major drug metabolism enzyme CYP2C9. This gene is highly polymorphic, and no-function (CYP2C9*3) plus decreased function (CYP2C9*2, *5, *8 and *11) star alleles (haplotypes) are commonly used to predict CYP2C9 metabolic ...

Genetic abnormality of cytochrome-P2C9*3 allele predisposes to epilepsy and phenytoin-induced adverse drug reactions: genotyping findings of cytochrome-alleles in the North Indian population

Future Journal of Pharmaceutical Sciences, 2022
Background This research aims to study the association of genetic polymorphism in genes coding for CYP2C9 and CYP2C19 in phenytoin-induced dose-related toxicity and to assess if the presence of allele CYP2C9*3 plays a role in phenytoin-induced ...

Quantitative assessment of the effect of cytochrome P450 2C9 gene polymorphism and colorectal cancer. [PDF]

PLoS ONE, 2013
CYP2C9 enzyme activity is involved in the metabolism of substances related to colorectal cancer (CRC), and it is functionally linked to a genetic polymorphism.
