Genetic variation affects drug-metabolizing enzymes, transporters, and target proteins, as well as immune-related proteins that may impact medication response. Genetic polymorphisms may influence medication effectiveness and risk for toxicity. Pharmacogenomics is the study of the impact of genetic polymorphisms on medication response. The goals of pharmacogenomics are to optimize medication efficacy and limit toxicity based on an individual’s DNA. Single nucleotide polymorphisms are the most common gene variations associated with medication response. Evidence-based resources, such as US Food and Drug Administration medication labels, Clinical Pharmacogenetics Implementation Consortium Guidelines, and the Pharmacogenomics Knowledgebase, are available to help clinicians select and dose medications based on a patient’s genetic profile. The pharmacist plays a key role in advancing pharmacogenomics in clinical practice as part of a multidisciplinary healthcare team.
