The Clinical Pharmacogenetics Implementation Consortium (CPIC) was formed in 2009 between PharmGKB and the Pharmacogenomics Research Network to address barriers to implementing pharmacogenetic tests in clinical practice. CPIC publishes peer-reviewed guidelines in a journal and on PharmGKB for using genetic information in drug therapy. Their guidelines provide gene-drug pairs and contact information for authors on published and underway guidelines to help with pharmacogenomic treatment.
