Family, twin, and adoption studies have demonstrated that genes play an important role in the development of alcoholism. We investigated the association between alcoholism and the genetic polymorphisms of the GABAA receptor genes on chromosome 5q33-34 in Korean population. The genotype of the GABAA receptor gene polymorphisms were determined by performing polymerase chain reaction genotyping for 172 normal controls and 162 male alcoholics who are hospitalized in alcoholism treatment institute. We found a significant association between the genetic polymorphisms of the GABAA alpha1 and GABAA alpha6 receptor gene and alcoholism. The GG genotype of the GABAA alpha1 receptor gene was associated with the onset age of alcoholism and alcohol withdrawal symptoms, and a high score on the Korean version of the ADS. However, there was no association between the genetic polymorphisms of the GABAA beta2 and gamma2 receptor gene and alcoholisms. Our finding suggest that genetic polymorphisms of the GABAA alpha1 and GABAA alpha6 receptor gene may be associated with the development of alcoholism and that the GG genotype of the GABAA alpha1 receptor gene play an important role in the development of the early onset and the severe type of alcoholism.
家族、双胞胎和收养研究表明,基因在酒精中毒的发展过程中起着重要作用。我们调查了韩国人群中酒精中毒与5号染色体q33 - 34上GABAA受体基因的基因多态性之间的关联。通过对172名正常对照者和162名在酒精中毒治疗机构住院的男性酒精中毒患者进行聚合酶链反应基因分型,确定了GABAA受体基因多态性的基因型。我们发现GABAAα1和GABAAα6受体基因的基因多态性与酒精中毒之间存在显著关联。GABAAα1受体基因的GG基因型与酒精中毒的发病年龄、戒酒症状以及韩国版酒精依赖量表(ADS)的高分相关。然而,GABAAβ2和γ2受体基因的基因多态性与酒精中毒之间没有关联。我们的研究结果表明,GABAAα1和GABAAα6受体基因的基因多态性可能与酒精中毒的发展有关,并且GABAAα1受体基因的GG基因型在早发性和严重型酒精中毒的发展中起重要作用。
