Association analysis of the dopamine receptor D2 (DRD2) SNP rs1076560 in alcoholic patients.


The dopamine system plays a well-established role in alcoholism. In this study, we examined the association between the single-nucleotide polymorphism (SNP) rs1076560 of the dopamine receptor D2 (DRD2) gene and susceptibility to alcoholism. SNP rs1076560 (C/A) is located in intron 6 of DRD2, where it is 1.4 kb downstream from alternative exon 6 and 83 bp… (More)
