在这项研究中,对365名墨西哥裔美国酗酒者和337名非酗酒者的多巴胺受体D4(DRD4)基因外显子3中一个48bp序列的可变数目串联重复(VNTR)多态性进行了基因分型。逻辑回归分析表明,不含有7次重复等位基因的基因型是酗酒的风险因素。然而,线性回归未发现DRD4 VNTR与MAXDRINKS(定义为24小时内饮酒的最大数量)之间存在关联。我们的研究结果表明,在墨西哥裔美国人中,DRD4 VNTR与酗酒之间存在关联。
In this study, the variable number tandem repeats (VNTR) polymorphism of a 48-bp sequence located in exon 3 of the dopamine receptor D4 (DRD4) gene was genotyped in 365 alcoholic and 337 non-alcoholic Mexican Americans. Logistic regression showed that genotypes without the 7-repeat allele were risk factors for alcoholism. However, linear regression did not find an association between DRD4 VNTR and MAXDRINKS, which was defined as the maximum number of drinks consumed within 24 hours. Our results indicate the presence of an association between DRD4 VNTR and alcoholism in Mexican Americans.
