Pharmacogenetic testing combines pharmacology and genomics with the intent of discovering effective and safe medications and doses tailored to a person’s genetic makeup. A number of commercially available panel tests (e.g., GeneSight® Analgesic, Proove® Opioid Risk Panel, Pain Medication DNA Insight™, Millennium PGT™, IDgenetix®) have been proposed as an aid in pain management.
Individual or panel tests relevant to pharmacogenetics could include testing of the following genes:
5HT2C (serotonin receptor gene)
5HT2A (serotonin receptor gene)
SLC6A4 (serotonin transporter gene)
DRD1 (dopamine receptor gene)
DRD2 (dopamine receptor gene)
DRD4 (dopamine receptor gene)
DAT1 or SLC6A3 (dopamine transporter gene)
DBH (dopamine beta-hydroxylase gene)
COMT (catechol O-methyltransferase gene)
MTHFR (methylenetetrahydrofolate reductase gene)
γ-aminobutyric acid (GABA) A receptor gene
OPRM1 (μ-opioid receptor gene)
OPRK1 (κ-opioid receptor gene)
UGT2B15 (uridine diphosphate glycosyltransferase 2 family, member 15)
Cytochrome p450 genes: CYP2D6, CYP2C19, CYP2C9, CYP3A4, CYP2B6, CYP1A2
Pharmacogenetic testing for the treatment of pain is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits, or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
No high quality studies were found in the published literature that validates the use of pharmacogenetic testing for the treatment of pain. At present, the clinical utility of pharmacogenetic testing in pain management is poorly defined.
