Test ID: PSYGP
Psychotropic Pharmacogenomics Gene Panel, Varies
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Individualizing selection and dosage of medications prescribed for treatment of depression and other psychiatric disorders based on genetic variation
Identifying genetic variation in genes known to be associated with response and/or risk of toxicity with psychotropic medications
Evaluating patients who have failed therapy with selective serotonin reuptake inhibitors (SSRIs)
Evaluating patients with treatment-resistant depression
Predicting response time to improvement with SSRIs
Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request
This test includes targeted testing to evaluate the following genes: ANKK1, ADRA2, CHRNA3, COMT, CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4, CYP3A5, DRD2, EPHX1, GRIK4, HLA-A*31:01, HLA-B*15:02, HTR2A, HTR2C, MTHFR, OPRM1, SCN1A, SLC6A4 (5-HTT), UGT2B15.
CYP2D6 testing is done in 2 tiers when needed. Tier 1 uses a PCR-based 5'-nuclease assay to determine the variants present. All samples also have copy number determined by PCR-based 5'-nuclease assay. Testing in tier 1 allows for the detection of all common CYP2D6 variants (eg, *2, *3, *4, *5, *6, *7, *8, *9, *10, *17, *29, *35, *41) and rarer alleles such as *11, *12, *14A, *14B, and *15. Duplications and multiplications of alleles are also identified. Unitary and tandem CYP2D7-2D6 (*13) alleles and CYP2D6-2D7 (eg, *4N, *36, and *68) alleles can also be detected. Tier 2 testing involves sequencing using fluorescent dye-terminator chemistry and is only done if an ambiguous phenotype results from tier 1 testing. Approximately 3% of samples require tier 2 testing.
Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If a specimen requires follow-up for CYP2D6, then reflex testing will be performed as appropriate at an additional charge.
