and personality traits (Luo et al., 2006, 2007a, b) and may be related to the role of ADH enzymes in the development and maintenance of the dopaminergic system (Chambon, 1993). The 5' UTR AVPR1A SNP rs3759292, indicated in this study, is located 179 bp 5' to the microsatellite polymorphisms rs9325177 and rs11283312 that were linked to autism, personality traits and altruism (Knafo et al., 2008, Meyer-Lindenberg et al., 2008, Wassink et al., 2004). DBI SNP rs2289948, indicated in this study, is in complete LD with SNP rs8192506 that was associated with alcoholism in Japanese (Waga et al., 2007) and with anxiety disorders with panic attacks in EA (Thoeringer et al., 2007). The second DBI SNP rs12613135, indicated in this study, is located in the same haplotype block with SNPs rs2289948 and rs8192506. The diazepam binding inhibitor may play a role in both physical and psychological dependence on opiates as well as anxiety disorders, as indicated by rat studies (Liu et al., 2005). GAD2 SNP rs2058725, from this study, is in the same haplotype block and in complete LD with SNP rs701492 which was associated with alcoholism in Han Taiwanese (Loh El et al., 2006). Other GAD2 SNPs showed association with
