Focused Pharmacogenomics Panel, Varies

Useful For Suggests clinical disorders or settings where the test may be helpful

Preemptive or reactive genotyping of patients for pharmacogenomic purposes

 

Providing an assessment for genes with strong drug-gene associations

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:

CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP3A4, CYP3A5, SLCO1B1, VKORC1, CYP4F2, and rs12777823.

 

CYP2D6 testing is done in 2 tiers when needed. Tier 1 uses a polymerase chain reaction (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, *14, *15, and *114. 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.
