It was investigated whether the allele A9 of the dopamine transporter gene (DAT1; SLC6A3) is associated with alcoholism, delirium tremens (DT), alcohol withdrawal seizures (AWS), or the daily alcohol intake.
Previous studies have found an association between the A9 allele (nine-copy repeat) of the dopamine transporter (DAT) gene and two complications of alcohol withdrawal, namely delirium tremens (DT) and alcohol withdrawal seizures (AWS).
