PharmVar updates for CYP3A4 star allele definitions

PharmVar announces several updates for CYP3A4 star allele definitions. Retirement of the CYP3A4*1G allele: this allele was defined by a common variant in intron 10 (c.1026+12G>A) which was also found on many other haplotypes (or star alleles). PharmVar transiently designated the CYP3A4*1G allele as

CYP4F2 is now fully curated by PharmVar

CYP4F2 contributes to the synthesis of cholesterol, steroids and other lipids. It has been shown to regulate the bioavailability of vitamin E and vitamin K, a co-factor that is critical to blood clotting. Variations in this important pharmacogene can affect vitamin K levels and thus, the dosing of vitamin K

PharmGKB selected in the first list of Global Core Biodata Resources

We are pleased to announce that PharmGKB is included in the first list of Global Core Biodata Resources (GCBRs), a collection of resources whose long term funding and sustainability is critical to life science and biomedical research worldwide. The Global Biodata Coalition (GBC) brings together major public and charitable funders,

CYP2C18 and knowledge gaps

Pablo Zubiaur & Andrea Gaedigk have an editorial online ahead of print in Pharmacogenomics calling for the inclusion of CYP2C18 in more studies of drug metabolism [PMID: 36331025]. CYP2C18 is in a cluster on chromosome 10 that has CYP2C18, CYP2C19, CYP2C9 and CYP2C8 that spans 500k bases (NCBI gene browser)

PharmCAT Version 2.0 Released

Version 2.0 of the Pharmacogenomics Clinical Annotation Tool (PharmCAT) has been released October 20, 2022. PharmCAT is a software tool that takes the genetic data (VCF file) of an individual as input, interprets the pharmacogene alleles, diplotypes, and phenotypes, and generates a report with genotype-based drug prescribing recommendations. In

There is no ontology term for Phenoconversion in BioPortal

There are two papers ahead of print in Pharmacogenomics both discussing how important phenoconversion is to consider in the implementation of PGx in clinical practice. Phenoconversion in the PGx context is a drug-drug interaction that impacts a drug metabolizing phenotype such that it mimics the effects of a metabolizer genotype.

New tutorial and walkthrough videos now available

We are pleased to announce the release of our PharmGKB walkthroughs and tutorial videos on YouTube. Users can now view detailed video walkthroughs of each of the main annotation types on PharmGKB as well as a longer video combining resources from across the site. We have also produced a series

PharmGKB and Reactome collaborate on two pathways

PharmGKB has collaborated with Reactome for two new pharmacokinetics pathways, Ribavirin, and Prednisone and Prednisolone available via both formats: Ribavirin Pathway, Pharmacokinetics on Reactome on PharmGKB Prednisone and Prednisolone Pathway, Pharmacokinetics on Reactomeon PharmGKB

Study of vitamin K pathways presents potential new warfarin candidates

Almost two decades after the cloning of VKORC1 and association with warfarin dose, a new pathway of vitamin K cycling has been published. Mishima et al [PMID:35922516] report on the Ferroptosis suppressor protein 1 (FSP1), coded for by the AIFM2 gene, and its mechanism of maintaining vitamin K in

PharmVar GeneFocus paper for SLCO1B1 is published

The PharmVar GeneFocus: SLCO1B1 paper has just been published by Clinical Pharmacology & Therapeutics. This review provides a general overview of SLCO1B1 as well as a deeper dive into its nomenclature. This GeneFocus covers genetic variability, functional impact, clinical relevance, gene nomenclature before and after PharmVar updates, methods for allele
