Clinical Utility of Pharmacogenomics of Psychotropic Medications

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

While the scientific understanding of pharmacogenomics is quickly accelerating, its translation to clinical decision-making (especially in psychiatric practice) has progressed more slowly. In an effort to begin to bridge this translational gap, genetic testing has been developed for various and commonly existing psychiatric disorders, such as major depression, schizophrenia, bipolar disorder, and pain syndromes to improve the safety of prescribing psychotropic medications for these disorders. This genetic testing incudes several pharmacodynamics and pharmacokinetic genetic factors, such as the cytochrome P450 1A2 gene (CYP1A2); the cytochrome P450 2B6 (CYP2B6) gene; P450 2D6 gene (CYP2D6); the cytochrome P450 2C9 gene (CYP2C9); the cytochrome P450 2C19 gene (CYP2C19); uridine-glucoronyl-transferase 2B15 (UGT2B15) gene; the serotonin transporter gene (Solute Carrier Family 6 Member; SLC6A4); p-glycoprotein ( ATP-binding cassette sub-family B member 1; ABCB1) transporter gene; the serotonin 2A receptor gene (HTR2A); the serotonin 2C receptor (HTR2C) gene; serotonin 1a receptor (5HT1a) gene; dopamine 1 receptor (DRD1) gene; dopamine 2 receptor (DRD2) gene; adrenergic alpha-2A receptor (alpha-2A) gene; opioid mu (opioid receptor mu 1; OPRM1) receptor gene; dopamine synthesis gene (ankyrin repeat and kinase domain containing 1; ANKK1); dopamine metabolizing enzyme \[Catechol-o-methyltransferase (COMT\]) gene; kainite receptor gene (glutamate ionotropic receptor kainate type subunit 4; GRIK4); folate (methylenetetrahydrofolate reductase; MTHFR) gene; sodium channels (sodium voltage-gated channel alpha subunit 2; SCN2A) gene. The interpretive report is based on copies of these multiple informative genes. The investigators are proposing to utilize comprehensive genetic testing to select more genetically-informed psychotropic medications to enhance their effectiveness in real-world patients with psychiatric illnesses such as schizophrenia, major depression, bipolar affective disorder as well as pain in a state hospital setting. The investigators plan to use genetic testing offered by Admera® for major classes of psychotropic medications. The investigators hypothesize that genetic testing will demonstrate clinical benefits by improving state hospital patients' response and decreasing their adverse effects. The proposed study will be conducted in a total sample of 60 subjects diagnosed with schizophrenia, major depression, bipolar affective disorder as well as pain at the Oregon State Hospital, Salem Oregon over a total period of 24 months
