Allele and genotype frequencies of the TaqI A polymorphism of dopamine D2 receptor (DRD2) gene were compared in 115 alcohol-dependent Brazilian males and 114 ethnically matched controls. Regression analyses were performed to test for an interactive effect between the DRD2 TaqI A1 allele and measures of stress and harm avoidance on severity of alcoholism and(More)

The presence of the seven-repeat allele of the VNTR in the exon 3 of the dopamine D4 receptor gene (DRD4) has been associated in healthy subjects to the personality trait of novelty seeking. The present study focuses these observations on a sample of Brazilian male alcoholics, evaluated on the temperament dimensions originally described by Cloninger. The(More)
