dbSNP: rs1799971
rs1799971
0.070 GeneticVariation BEFREE In this meta-analysis, the results indicate the OPRM1 A118G polymorphism was associated with the opioid requirement and the adverse effects in pain treatment especially in postoperative pain. 31337162

dbSNP: rs1799971
rs1799971
0.070 GeneticVariation BEFREE OPRM1-A118G polymorphism (A > G, rs1799971) is associated with interindividual variability in both response to postoperative pain and opioid treatment. 30323865

dbSNP: rs1799971
rs1799971
0.070 GeneticVariation BEFREE Using multiple regression analyses, four single-nucleotide polymorphisms of COMT (rs6269, rs4633, rs4818, and rs4680), their haplotypes, and diplotypes were considered for their interactions with A118G of OPRM1 regarding postoperative pain and opioid consumption. 27903758

2017

dbSNP: rs1799971
rs1799971
0.070 GeneticVariation BEFREE The OPRM1 A118G polymorphism may help predict individuals' response to epidural labor analgesia and so optimize postoperative pain control. 23909491

2013

dbSNP: rs1799971
rs1799971
0.070 GeneticVariation BEFREE The aim of the study was to search for an association between the single-nucleotide polymorphisms A118G in OPRM1 and C3435T and G2677T/A in ABCB1 and the analgesic effect of intravenous oxycodone in postoperative pain. 21383334

2012

dbSNP: rs1799971
rs1799971
0.070 GeneticVariation BEFREE This study shows that the OPRM1 118A>G polymorphism affects postoperative pain response in heterozygous patients: they have a different postoperative pain response than patients with wild-type genes, which may affect the efficacy of the analgesic therapy. 22230405

2012

dbSNP: rs1799971
rs1799971
0.070 GeneticVariation BEFREE These results suggest that the A118G SNP may moderate but not mediate the effects of anger-out on postoperative pain responses. 16400534
