NCBI Description of OPRM1

The OPRM1 gene encodes the mu opioid receptor, which is the primary site of action for the most commonly used opioids, including morphine, heroin, fentanyl, and methadone. It is also the primary receptor for endogenous opioid peptides beta-endorphin (see POMC, MIM 176830) and the enkephalins (see PENK, MIM 131330). The OPRM1 receptor is a membrane of the G protein-coupled receptor family (Bond et al., 1998 [PubMed 9689128]). There are at least 3 types of opioid receptors, mu, kappa (OPRK1; MIM 165196), and delta (OPRD1; MIM 165195), each with a distinct pharmacologic profile (Chen et al., 1993 [PubMed 8393525]).[supplied by OMIM, Oct 2009].;This gene encodes one of three opioid receptors. The mu opioid receptor is the principal target of endogenous opioid peptides and opioid analgesic agents such a s beta-endorphn and enkephalins. The NM_001008503.1:c.118A>G allele had been associated with opioid and alcohol addiction and variations in pain sensitivity but evidence is conflicting. Multiple transcript variants encoding different isoforms have been found for this gene.
