Scientific evidence indicates that pharmacogenetics, the study of drug interactions with an individual’s genetic makeup, may improve patient safety. Pharmacogenetic testing for some medications adds genetic information to the usual considerations of patient age, weight, disease process, use of other medications, health behaviors and environment. The additional information gained from pharmacogenetics can help prescribers choose and dose medication that best meets the needs of the individual patient.
Patient / Parent Education
Our Genetic Pharmacology Service (GPS) provides education about pharmacogenetics, clinical pharmacology and genetic testing. Prior to testing, families can download the Gene Test for Medicines: Patient/Parent Information handout to find answers to frequently asked questions about pharmacogenetic testing. This handout can be downloaded in English or Spanish and is designed to help you decide whether to have pharmacogenetics testing.
Families considering TPMT testing can download the TPMT Testing Parent Information handout. A TPMT test is a specific pharmacogenetic test. It checks for certain forms of a gene called thiopurine s-methyltransferase (TPMT).
Psychiatry Pharmacogenetics Expanded Panel Test Result Information
GPS patient handouts (101-210, below) provide an explanation of test results for patients who have recently been tested for the Psychiatry Pharmacogenetics Expanded Panel. The Psychiatry Pharmacogenetics Expanded Panel tests for differences in two genes, CYP2C19 and CYP2D6. Therefore, two GPS patient handouts are associated with each Psychiatry Pharmacogenetics Expanded Panel test result.
Contact your clinician to identify the GPS patient handouts that correlate to your unique Psychiatry Pharmacogenetics Expanded Panel test results. The GPS patient handouts are available for download:
GPS Patient Handouts: CYP2C19
GPS Patient Handouts: CYP2D6
