摘要: Background: Alcohol dependence (AD) vulnerability is determined by a complex array of genetic factors. Given the potential role endocannabinoid system in AD, polymorphisms within cannabinoid receptor 1 gene (CNR1) have been potentially associated with susceptibility to this disease. We thus aimed examine relationship between 3 allelic variants CNR1 (rs6454674, rs1049353, and rs806368) AD. Methods: Genotyping aforementioned was carried out PCR 298 male alcoholics (187 them AD) 155 healthy controls. Single-marker, haplotype, interaction analysis were performed analyze influence on AD susceptibility. Results: found an association after haplotype analysis. Alcoholic patients TGT (corresponding rs6454674-rs1049353-rs806368 order) less prone (p = 0.017). Besides, G/T substitution first marker (GGT haplotype) or C/T third (TGC more likely develop (p = 0.006 0.004, respectively) G allele rs6454674 single nucleotide polymorphism (SNP) C rs806368 SNP (p = 0.009). Conclusions: Our findings support previously reported associations alcohol other substances emphasizes relevance AD.
