Genetic analysis of the association between alcohol, cocaine, and opiate addiction and variable number tandem repeat (VNTR) polymorphisms in monoamine oxidase B (MAOB) and serotonergic 5-hydroxytryptamine (serotonin) receptor 1B and 2C (HTR1B 21 and HTR2C) pathway genes was performed in a sample of 302 polyconsumers. Our genetic association analysis revealed a significant association between a 184 base pair (bp) VNTR polymorphism in the MAOB gene and addiction to cocaine and opiates. This work highlights new genetic marker associations in cocaine and opiate polyconsumer addictions. These data help to clarify and quantify the complex role of genetics in addictive disorders, as well as their future contribution to the prevention (genetic counselling), diagnosis (genetic diagnosis of vulnerability), and treatment (pharmacogenomics) of these disorders.
对302名多种药物滥用者样本进行了酒精、可卡因和阿片类成瘾与单胺氧化酶B（MAOB）以及血清素能5-羟色胺（血清素）受体1B和2C（HTR1B 21和HTR2C）途径基因中的可变数目串联重复（VNTR）多态性之间关联的基因分析。我们的基因关联分析揭示了MAOB基因中一个184碱基对（bp）的VNTR多态性与可卡因和阿片类成瘾之间存在显著关联。这项研究突出了可卡因和阿片类多种药物滥用成瘾中新的基因标记关联。这些数据有助于阐明和量化遗传学在成瘾性疾病中的复杂作用，以及它们未来对这些疾病的预防（遗传咨询）、诊断（易感性的基因诊断）和治疗（药物基因组学）的贡献。
