Abstract:

Objective To investigate the association between rs1799971 polymorphism in mu opioid receptor 1 (OPRM1) gene and susceptibility of alcohol dependence. Methods Through five online databases including PubMed, Web of Science, EMBASE, CNKI, and Wanfang electronic database, the studies related to the research objective were accessed, and the search deadline was on July 10, 2020. And the selected literature is based on the established inclusion criteria and exclusion criteria, and the included studies subjects is assess the quality using the Newcastle-Ottawa Scale (NOS). The data was merged by RevMan5.3 software, the allele model (A vs. G), homozygous model (AA vs. GG), heterozygous model (AG vs. GG), dominance model (AA+AG vs. GG) and recessive model (AA vs. AG+GG) P value, odds ratio (ORs) and 95% confidence interval (95% CIs) was calculated. Results A total of 22 studies with 24 independent researches were included in the meta-analysis. All eligible studies received five or more NOS scores and were in favorable quality for the included methodology. The results suggested that rs1799971 polymorphism was associated with alcohol dependence (P=0.03). Subgroup analysis indicated the association only existed in the asian population. Especially AG-genotype carriers had an increased risk of alcohol dependence. Conclusion Rs1799971 polymorphism in OPRM1 gene is significantly associated with the risk of alcohol dependence in Asians, especially AG-genotype carriers have an elevated alcohol dependence risk.
