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 indexed in PubMed as clinical guidelines, endorsed by ASHP and ASCPT, and referenced in ClinGen and PharmGKB.

Additionally, the College of American Pathologists (CAP)  has stated: “CAP applauds and supports the objectives, processes and work completed as of December 2018 by the Clinical Pharmacogenetics Implementation Consortium (CPIC®). These efforts will help clinicians, laboratories, health care providers and vendors.”

  • New CPIC Guideline: CYP2C9 and Nonsteroidal Anti-inflammatory Drugs (NSAIDs) March 26, 2020
    The CPIC Guideline for CYP2C9 and Nonsteroidal Anti-inflammatory Drugs (NSAIDs) is now published in Clinical Pharmacology and Therapeutics. The accepted article can be accessed on the PharmGKB pages for a number of NSAIDs drugs, CYP2C9, and on the CPIC website.p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica} Nonsteroidal Anti-inflammatory Drugs (NSAIDs) are among the most commonly prescribed drugs to treat […]
  • FDA releases tables on the use of pharmacogenetic testing for specific medications February 23, 2020
    CPIC and PharmGKB applaud the release of additional guidance from the FDA on the use of pharmacogenetic testing for specific medications. Numerous members of the pharmacogenetics implementation community have asked CPIC and PharmGKB for our views on the FDA release and we identify some similarities and differences below.There are substantial areas of overlap in those […]
  • Centralized presentation material repository now available from CPIC’s PGx Dissemination working group February 10, 2020
    The CPIC’s PGx Dissemination working group has developed a central repository for pharmacogenomic-related presentation materials.  Now available on the PGRN website (, users will find a resource link “discussion forum” at The discussion forum provides a medium to disseminate links to PGx presentation materials and handouts.If you have a resource that you would like […]
  • PharmGKB and CPIC support H.R. 3235 (updated 1/27/20) January 27, 2020
    PharmGKB and CPIC have signed up as supporters of H.R. 3235, the ‘Access to Genetic Counselor Services Act’. This bill would improve access to genetic counseling for Medicare beneficiaries by recognizing genetic counselors as independent healthcare providers who can be reimbursed for their services. Dr. Teri Klein, co-PI of PharmGKB and CPIC, said: “Genetic counselors […]
  • CPIC launches second Term Standardization project – seeking PGx experts December 17, 2019
    CPIC leadership has put out a call for gene experts to participate in the second CPIC Term Standardization project, which will begin in early 2020.This project continues the work of the first term standardization effort in 2016, where standardized terms for pharmacogenetic (PGx) allele function and associated phenotypes were developed and agreed upon by a […]
