Previous research has suggested that similar gene variants of both the dopamine D2 receptor gene (DRD2) and the dopamine transporter gene (DAT1) may be associated with a number of addictive behaviors (i.e. alcoholism, substance abuse, and nicotine dependence). In this study of 129 individuals, the authors found an association of the DRD2 A1 allele and Schizoid/Avoidant behaviors (SAB). The severity of the SAB increased with increasing frequency of the DRD2 A1 allele gene pattern.
