Call for clarification on antidepressant pharmacogenomics

A new Perspective in Clinical Pharmacology and Therapeutics outlines the need for improved communication from pharmacogenomic testing companies and regulators on the role of pharmacogenomics in antidepressant therapy.Beginning antidepressant treatment can be an arduous experience for patients. Some patients fail to respond to first-line antidepressants, leading to an iterative

CYP2D6 Genotype to Phenotype Standardization Project results published

The consensus of the CYP2D6 Genotype to Phenotype Standardization Project is just published in Clinical and Translational Science. To address inconsistencies in the translation of CYP2D6 genotype to phenotype across guidelines (i.e. Clinical Pharmacogenetics Implementation Consortium (CPIC) and Dutch Pharmacogenetics Working Group (DPWG)) and between clinical genetic testing laboratories,

Public comment period for CPIC allele function assignment SOP

CPIC is inviting public comments on their draft SOP for assigning function to pharmacogenomic alleles.CPIC has been assigning “function” to pharmacogenomic alleles since its inception. This has already led to a Delphi process and consensus publication on standardizing terms used for allele function and pharmacogenetic phenotypes for some genes.

ACLA writes to the FDA about PGx testing

The American Clinical Laboratory Association (ACLA) has written a letter to the US Food and Drug Administration (FDA) regarding the FDA’s recent communications about pharmacogenomic (PGx) testing. The letter details the ACLA’s concerns that the FDA’s actions will have a significant impact on both patients and the

Michelle Whirl-Carrillo -- Director of the PharmGKB!

We are happy to announce that Dr. Michelle Whirl-Carrillo has agreed to take on the position of Director of PharmGKB. Michelle has worked with the PharmGKB for over 15 years (not including a 1.5 year “sabbatical” at 23andme). She has served as lead curator, Assistant Director, and (since 2014)

CPIC to issue guidance on non-actionable pharmacogenes

The Clinical Pharmacogenetics Implementation Consortium (CPIC) hopes to provide more guidance in the future about gene-drug pairs which have a weak evidence base and are not clinically actionable, despite being heavily marketed to healthcare providers and the public. Many of these gene-drug pairs have already been curated by CPIC staff

PharmVar core alleles to be used by PharmGKB and CPIC

PharmVar has released core alleles - single, rule-based definitions per star allele distilled from the respective suballeles - for the cytochrome P450 genes CYP2C9, CYP2C19, and CYP2D6. Only sequence variations that change an amino acid or impact function by changing expression levels or interfere with splicing and are present in

New CPIC Guideline: CYP2B6 and efavirenz

The CPIC Guideline for CYP2B6 and efavirenz is now published in Clinical Pharmacology and Therapeutics. The accepted article can be viewed on the PharmGKB pages for efavirenz, CYP2B6, and on the CPIC website. Efavirenz is a non-nucleoside reverse transcriptase inhibitor widely used worldwide to treat HIV-1 infection. It is predominantly

CYP2C19 testing may assist with prescribing sertraline and escitalopram

Mary Relling (St. Jude Children's Research Hospital) and I (Teri Klein) as Co-Principal Investigators of the Clinical Pharmacogenetics Implementation Consortium (CPIC) have been discussing the letter that the FDA recently sent to a genomics laboratory expressing concern that “providers may make inappropriate treatment decisions based” on pharmacogenetic testing

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
