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).
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.
We reanalyzed the role of the DAT gene in the lifetime risk for AWS and DT in 120 alcohol-dependent patients, taking into account potentially confounding factors.
