  • The MAO-A gene, platelet MAO-B activity and psychosocial environment in adolescent female alcohol-related problem behaviour
  • 2008

    • Background: Antisocial behaviour has been associated with polymorphic variants in candidate genes and recently also gene-environmental interaction models have been presented. It has been suggested that antisocial behaviour, associated with alcohol consumption in males, is related to a variation in the monoamine oxidase A gene (MAO-A) promoter. Furthermore, platelet MAO-B activity has in several studies been reported to be low in male alcoholics, while this has not been the case with regard to female alcoholics. Aims of the present study were to: (1) investigate possible interactions between the MAO-A polymorphism, family relations and maltreatment/sexual abuse on adolescent alcohol-related problem behaviour among female adolescents; (2) to investigate if platelet MAO-B enzyme activity interacted with environment to predict female alcohol-related problems. Methods: A random sample of 114 female individuals from a total population of 16- and 19-year adolescents from a Swedish county, who volunteered to participate in the study, were interviewed, filled in a questionnaire and a blood sample was drawn. Results: In contrast to what has been reported in males, presence of the long (4-repeat) variant of the MAO-A gene in females interacted significantly with an unfavourable environment (poor family relations or maltreatment/abuse/sexual abuse) to increase the risk for high scores of alcohol-related problems. Furthermore, females with low platelet MAO-B activity showed an increased risk of alcohol-related problem behaviour in an unfavourable environment. Conclusions: Poor psychosocial environment interacts with the high activity MAO-A genotype and low platelet MAO-B enzyme activity to increase vulnerability for female adolescent alcohol-related problem behaviour.

    • AIM: To investigate possible interactions between a polymorphism in the monoamine oxidase A (MAO-A) gene promoter, family relations and maltreatment/sexual abuse on adolescent alcohol-related problem behaviour among male adolescents. DESIGN, SETTING AND PARTICIPANTS: A cross-sectional study of a randomized sample of 66 male individuals from a total population of 16- and 19-year adolescents from a Swedish county. Boys, who volunteered to participate answering an alcohol-related problem/behaviour questionnaire, were investigated with regard to interactions between such problems, family function, maltreatment and MAO-A genotype. MEASUREMENTS: MAO-A genotype, family relations history, history of being maltreated or abused and alcohol-related problem behaviour. FINDINGS: Boys with the short (three-repeat) variant of the MAO-A gene, who had been maltreated/abused or came from families with poor relations, showed significantly higher scores of alcohol-related problems. We also found that maltreatment/abuse independently showed the strongest relation to alcohol-related problems among boys in our model. CONCLUSIONS: The results suggest that both maltreatment and MAO-A genotype may be useful for the understanding of male adolescent alcohol-related problem behaviour.

  • Adolescent girls and criminal activity : Role of MAOA-LPR genotype and psychosocial factors
  • 2007
  • Ingår i: American Journal of Medical Genetics Part B. - Uppsala Univ, Cent Hosp Vasteras 1, Clin Res Ctr, S-72189 Vasteras, Sweden. Uppsala Univ, Dept Neurosci, Pharmacol Unit, S-75105 Uppsala, Sweden. : Wiley. - 1552-4841 .- 1552-485X. ; 144:2, s. 159-164
  • Tidskriftsartikel (refereegranskat)abstract
    • Recent findings among boys show that interactions between a polymorphism in the monoamine oxidase A gene promoter region (MAOA-LPR) and psychosocial factors predict criminal activity. The objective of this study was to investigate whether this finding could be extended to adolescent girls. One hundred nineteen female adolescents were recruited among respondents to a cross-sectional study of the total population of 16- and 19-year old girls. These girls constituted a randomly selected sub-sample from groups representing different degrees of risk behavior. The subjects filled in a questionnaire and were interviewed and genotyped with regard to MAOA-LPR. The results indicate that the long, (4-repeat) allele confer an increased risk for criminal behavior in the presence of psychosocial risk. Among girls without social risk, MAOA-LPR genotype was of no importance for criminal behavior. The present results suggest that previous observations on adolescent males, which demonstrate that the short MAOA-LPR genotype and psychosocial adversity interact to predict criminal activity, may not be applicable to females.
