What is CPIC?

The Clinical Pharmacogenetics Implementation Consortium (CPIC®) is an international consortium of individual volunteers and a small dedicated staff who are interested in facilitating use of pharmacogenetic tests for patient care.

One barrier to implementation of pharmacogenetic testing in the clinic is the difficulty in translating genetic laboratory test results into actionable prescribing decisions for affected drugs.

CPIC’s goal is to address this barrier to clinical implementation of pharmacogenetic tests by creating, curating, and posting freely available, peer-reviewed, evidence-based, updatable, and detailed gene/drug clinical practice guidelines (click here for all CPIC publications).  CPIC guidelines follow standardized formats, include systematic grading of evidence and clinical recommendations, use standardized terminology, are peer-reviewed, and are published in a leading journal (in partnership with Clinical Pharmacology and Therapeutics) with simultaneous posting to, where they are regularly updated.

CPIC started as a shared project between PharmGKB and the Pharmacogenomics Research Network (PGRN) in 2009. CPIC guidelines are available on, indexed in PubMed as clinical guidelines, endorsed by ASHP and ASCPT, and referenced in ClinGen and PharmGKB.

  • CPIC Guideline Update: Carbamazepine, Oxcarbazepine and HLA genotype February 14, 2018
    The CPIC Guideline for carbamazepine, oxcarbazepine and HLA genotype is now published in Clinical Pharmacology and Therapeutics. The accepted article can be viewed on the PharmGKB pages for carbamazepine and oxcarbazepine and on the CPIC website. Carbamazepine and oxcarbazepine are anticonvulsants which have been approved for treatment for epilepsy and, in the case of carbamazepine, trigeminal neuralgia. Patients with the HLA-A*31:01 and/or the […]
  • New CPIC Guideline: CYP2D6 and tamoxifen January 31, 2018
    The CPIC Guideline for tamoxifen and CYP2D6 is now published in Clinical Pharmacology and Therapeutics. The accepted article can be viewed on the PharmGKB page for tamoxifen, and the CPIC website. Tamoxifen is a selective estrogen receptor modulator (SERM) and is utilized in breast cancer treatment. Tamoxifen is extensively metabolized, in part by CYP2D6. Patients with certain CYP2D6 genetic polymorphisms and […]
  • PharmCAT commentary in Clinical Pharmacology & Therapeutics December 1, 2017
    A commentary about the Pharmacogenomics Clinical Annotation Tool (PharmCAT) was recently published in Clinical Pharmacology & Therapeutics.  PharmCAT is developed in a collaboration between the former PGRN Statistical Analysis Resource (P-STAR) and the Pharmacogenomics Knowledgebase (PharmGKB) with input from other groups (click here for a list of participants). PharmCAT will extract PGx variants, beginning with variants […]
  • CPIC Guideline Update: DPYD and Fluoropyrimidines November 21, 2017
    The 2017 update of the CPIC Guideline for Fluoropyrimidines and DPYD is now available as an advance online publication in Clinical Pharmacology and Therapeutics. CPIC extensively reviewed the literature up to March 2017. Both the dosing recommendations and supplemental information were updated. The accepted article can currently be viewed on the PharmGKB pages for capecitabine and fluorouracil, and the CPIC website. Fluoropyrimidines are mainly used to treat solid […]
