This study investigated whether college students carrying the dopamine transporter (DAT) 9 allele have higher frequencies of alcohol consumption. There were no significant associations found between DAT genotype and alcohol consumption. Since prior studies found more alcohol use disorder symptoms over time in those carrying the DAT 9 allele, these findings indicate that DAT genotype may play a role in the negative effects of drinking alcohol and not the act of drinking itself.
