mu-Opioid receptor agonists, such as morphine, are widely applied in pain therapy clinical practice. However, the effects exerted by morphine via receptor are influenced by individual specificity. Single nucleotide polymorphisms (SNPs) in mu-opioid receptor gene (OPRM1) have been reported to influence receptor expression and function. Subsequently, we analyzed SNPs frequency and linkage disequilibrium associated with OPRM1 transcriptional region and 4 exons among healthy Japanese individuals. Consequently, we detected 10 SNPs (-1748G/A, -1565T/C, -1045A/G, -172G/T, -38C/A, 118A/G, ivs2 31 G/A, ivs2 691 C/G, ivs4 274 A/G, and ivs4 435 G/A). Moreover, linkage analysis revealed novel linkage between -1748G/A and -172G/T, which was not observed in studies performed in other nations. In contrast, SNPs frequency detected in this study was similar to previously reported results on Asians; however, linkage disequilibrium reports from different nations differed. These results possibly provide useful information for OPRM1 genotyping in the Japanese population.
