Although multiple studies have shown the role genetics plays in personality
disorders and in addictions, few have studied the genetic aspects of their
comorbidity. Here, we carried out a cross-sectional study in a sample comprising 303 Caucasian polydrug-consuming patients. The presence of personality
disorders was evaluated using the International Personality Disorder Examination, and genes related to dopamine, serotonin and monoamine oxidase
(MAO) were genotyped. A significant relationship was observed between the
bp 279 DRD5 variable number of tandem repeat (VNTR) polymorphism and
paranoid personality disorder OR 95 ð Þ ð Þ¼ %CI 2:186 1ð Þ :074;4:449 ;p ¼ 0:006 .
The bp 182 OR 95 ð Þ ð Þ¼ %CI 0:407 0ð Þ :178;0:931 ;p ¼ 0:033 and bp
184 OR 95 ð Þ ð Þ¼ %CI 0:391 0ð Þ :188;0:813 ;p ¼ 0:012 alleles of the MAOB VNTR
were also associated with antisocial personality disorder. Among patients with
addictions, paranoid personality disorder should also be considered in addition
to the importance of antisocial and borderline personality disorders. The higher
frequency of the bp 279 DRD5 VNTR allele found in patients with paranoid personality disorder, as well as the associations between alleles of the MAOB VNTR
and antisocial personality disorder, support the monoaminergic bases of these
personality disorders, especially when dealing with patients with addictions. [-]
