Abstract

Recent investigations suggest that genetic susceptibility to alcohol dependence may be conferred by GABA(A) receptor subunit genes. In this study, three RFLPs at the GABA(A)beta 2 GABA(A)alpha 6, GABA(A)alpha 1 and two at the GABA(A)gamma 2 receptor subunit genes, were examined for association with alcohol dependence in 189 subjects meeting DSM-III-R criteria for this disorder and 152 unrelated controls from a Japanese population. The results demonstrated no association between the AlwNI RFLP at the GABA(A)alpha 6 receptor subunit gene and alcohol dependence (P = 0,059), However, the NciI RFLP at the GABA(A)gamma 2 receptor subunit gene was associated with alcohol dependence comorbid with antisocial personality disorder (P = 0.021), This supports a recent finding reporting an association between the GABA(A)gamma 2 receptor subunit gene and alcohol dependence with criminal record in a Finnish population. Taking into account the effects of multiple comparisons, this result should be interpreted with caution pending replication.
