Figure 1 presents the % frequency for each risk allele for each gene of interest. The MAO and DRD1 genes yielded the greatest frequency of homozygote alleles, whereas none of the subjects were homozygous for risk allele genes OPRMI, DRD4 (rs761010487), and DAT1f. A total GARS score of seven or greater qualifies as high risk for alcohol addiction. Our results showed that 76% of subjects fell into the high-risk category for alcohol addiction (Figure 2). The gene discussed is DRD1; the disease is Addictive alcohol use.
