    Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for CYP2D6 and CYP2C19 Genotypes and Dosing of Selective Serotonin Reuptake Inhibitors
    (Wiley, 2015-08) Hicks, J. Kevin; Bishop, Jeffrey R.; Sangkuhl, Katrin; Müller, Daniel J; Ji, Yuan; Leckband, Susan G.; Leeder, J. Steven; Graham, Rebecca L.; Chiulli, Dana L.; LLerena, Adrián; Skaar, Todd C.; Scott, Stuart A.; Stingl, Julia C.; Klein, Teri E.; Caudle, Kelly E.; Gaedigk, Andrea; Department of Medicine, IU School of Medicine
    Selective serotonin reuptake inhibitors (SSRIs) are primary treatment options for major depressive and anxiety disorders. CYP2D6 and CYP2C19 polymorphisms can influence the metabolism of SSRIs, thereby affecting drug efficacy and safety. We summarize evidence from the published literature supporting these associations and provide dosing recommendations for fluvoxamine, paroxetine, citalopram, escitalopram, and sertraline based on CYP2D6 and/or CYP2C19 genotype (updates at www.pharmgkb.org).

    Clinical Pharmacogenetics Implementation Consortium (CPIC) Guidelines for CYP3A5 Genotype and Tacrolimus Dosing
    (Wiley, 2015-07) Birdwell, Kelly A.; Decker, Brian; Barbarino, Julia M.; Peterson, Josh F.; Stein, C. Michael; Sadee, Wolfgang; Wang, Danxin; Vinks, Alexander A.; He, Yijing; Swen, Jesse J.; Leeder, J. Steven; van Schaik, RHN; Thummel, Kenneth E.; Klein, Teri E.; Caudle, Kelly E.; MacPhee, Iain A.M.; Department of Medicine, IU School of Medicine
    Tacrolimus is the mainstay immunosuppressant drug used after solid organ and hematopoietic stem cell transplantation. Individuals who express CYP3A5 (extensive and intermediate metabolizers) generally have decreased dose-adjusted trough concentrations of tacrolimus as compared with those who are CYP3A5 nonexpressers (poor metabolizers), possibly delaying achievement of target blood concentrations. We summarize evidence from the published literature supporting this association and provide dosing recommendations for tacrolimus based on CYP3A5 genotype when known (updates at www.pharmgkb.org).

    Clinical Pharmacogenetics Implementation Consortium Guideline for CYP2D6, OPRM1, and COMT Genotypes and Select Opioid Therapy
    (Wiley, 2021) Crews, Kristine R.; Monte, Andrew A.; Huddart, Rachel; Caudle, Kelly E.; Kharasch, Evan D.; Gaedigk, Andrea; Dunnenberger, Henry M.; Leeder, J. Steven; Callaghan, John T.; Samer, Caroline Flora; Klein, Teri E.; Haidar, Cyrine E.; Van Driest, Sara L.; Ruano, Gualberto; Sangkuhl, Katrin; Cavallari, Larisa H.; Müller, Daniel J.; Prows, Cynthia A.; Nagy, Mohamed; Somogyi, Andrew A.; Skaar, Todd C.; Medicine, School of Medicine
    Opioids are mainly used to treat both acute and chronic pain. Several opioids are metabolized to some extent by CYP2D6 (codeine, tramadol, hydrocodone, oxycodone and methadone). Polymorphisms in CYP2D6 have been studied for an association with the clinical effect and safety of these drugs. Other genes which have been studied for their association with opioid clinical effect or adverse events include OPRM1 (mu receptor) and COMT (catechol-O-methyltransferase). This guideline updates and expands the 2014 Clinical Pharmacogenetics Implementation Consortium (CPIC) guideline for CYP2D6 genotype and codeine therapy and includes a summation of the evidence describing the impact of CYP2D6, OPRM1 and COMT on opioid analgesia and adverse events. We provide therapeutic recommendations for the use of CYP2D6 genotype results for prescribing codeine and tramadol and describe the limited and/or weak data for CYP2D6 and hydrocodone, oxycodone and methadone and for OPRM1 and COMT for clinical use.

    Response to a drug often differs widely among individual patients. This variability is frequently observed not only with respect to effective responses but also with adverse drug reactions. Matching patients to the drugs that are most likely to be effective and least likely to cause harm is the goal of effective therapeutics. Pharmacogenomics (PGx) holds the promise of precision medicine through elucidating the genetic determinants responsible for pharmacological outcomes and using them to guide drug selection and dosing. Here we survey the US landscape of research programs in PGx implementation, review current advances and clinical applications of PGx, summarize the obstacles that have hindered PGx implementation, and identify the critical knowledge gaps and possible studies needed to help to address them.
