Table 3. Frequency of various haplotypes composed of Tag ID rs1800498 intron 2 (C/T), Tag IB rs1079597 intron 1 (A/G), and Tag IA rs1800497 Ex8 (A1/A2) SNPs of DRD2 receptor gene and ANKK1 gene in alcohol dependent subjects with a history of at least one suicidal attempt (n = 61) and in individuals in whom alcohol dependence was not associated with suicidal behavior (n = 108).
