New CPIC Guideline: CYP2D6 and atomoxetine

The CPIC Guideline for atomoxetine and CYP2D6 is now published in Clinical Pharmacology and Therapeutics. The accepted article can be viewed on the PharmGKB page for atomoxetine, and the CPIC website. Atomoxetine is a non-stimulant medication used in the treatment of attention-deficit/hyperactivity disorder. Atomoxetine is metabolized by CYP2D6 and

New CPIC guideline: potent volatile anesthetic agents and succinylcholine in the context of RYR1 or CACNA1S genotypes

The CPIC Guidelines for potent volatile anesthetic agents and succinylcholine in the context of RYR1 or CACNA1S genotypes is now published in Clinical Pharmacology and Therapeutics. The accepted article can be viewed on the PharmGKB pages for RYR1 and CACNA1S, and the CPIC website. Potent volatile anesthetic agents are used

CPIC Dosing Guidelines for DPYD and Fluoropyrimidines Updated

An update to the CPIC dosing guidelines for DPYD and fluoropyrimidines has recently been added to the CPIC and PharmGKB websites. The most recent version of the guideline, published in Clinical Pharmacology & Therapeutics in November 2017, recommended that patients who were DPYD intermediate metabolizers with an activity score of

New biogeographical groups in use at PharmGKB

Recent visitors to the PharmGKB website may have noticed a change in how we report racial and ethnicity information in our variant and clinical annotations. Until July 2018, PharmGKB used the US Office of Management and Budget (OMB) race categories with an additional ethnicity category of Hispanic/Latino. These groups

New PharmGKB pathways for methylphenidate

PharmGKB released two new pathways for methylphenidate. Methylphenidate is a central nervous system stimulant used for the treatment of attention deficit hyperactivity disorder and narcolepsy and elicits its effects by blocking the reuptake of the neurotransmitter dopamine and norepinephrine into the presynaptic neuron. The pharmacokinetics pathway depicts the metabolism and

CYP2D614A and 14B are updated to 114 and 14 based on the current PharmVar release

PharmGKB and CPIC revised the CYP2D6 allele names *14A and *14B to be in concordance with the latest major PharmVar release. CYP2D6*14A is revised to *114 and *14B to *14 in the variant and clinical annotations. The allele choices in the annotation of the CPIC guidelines for CYP2D6 have

Major PharmVar update released

PharmVar has announced the release of a major update to www.pharmvar.org. Notable new features include a revised haplotype naming system, the introduction of unique haplotype IDs, a functional impact display next to causative SNVs in brackets and a revised allele (CYP2D6*14A is now *114). The new gene

PharmGKB data used to establish a minimum genetic testing panel for psychiatry

The lack of standardization of which genes or alleles should be included in pharmacogenetic testing panels is a major barrier to the full implementation of pharmacogenomics in the clinic. In an effort to help clinicians select an appropriate pharmacogenetic test, Dr. Chad Bousman and Dr. Abdullah Al Maruf of the

DPYD genotyping implementation study published

In a journal article published online last week in The Lancet Oncology, Henricks et al. reported that DPYD genotype-based dose reductions of fluorouracil and capecitabine in cancer patients resulted in improved safety outcomes and was feasible in clinical practice. The authors prospectively genotyped four DPYD variants: rs3918290 (1905+1G>

PharmGKB oxycodone pathway published in Pharmacogenetics and Genomics

The PharmGKB Oxycodone Pathway, Pharmacokinetics is featured on the cover of the October 2018 issue of Pharmacogenetics and Genomics. Oxycodone is an opioid analgesic metabolized by CYP2D6 and CYP3A4/5 to a number of metabolites, including oxymorphone which itself can be used as an analgesic.The pathway was produced by
