Question

How should our society deal with genetic predispositions to violent behavior? A man who has committed several violent rapes is on trial and his lawyer argues that the man cannot help himself because his behavior is the result of his genetic makeup. The man's father and brother also have a history of committing violent crimes. In defense of this position, the lawyer cites studies reported in 1993 on a small Dutch family indicating that some people inherit a propensity toward violent behavior. Affected people in this family have a mutation in a gene involved in breakdown of neuro-transmitters. Genetic testing shows that this man and his father & brother have this same mutation In a large Dutch kindred, Brunner et al. (1993) identified a new form of X-linked nondysmorphic mild mental retardation. All affected males in the family showed characteristic abnormal behavior, in particular aggressive and sometimes violent behavior. Other types of impulsive behavior included arson, attempted rape, and exhibitionism. Attempted suicide was reported in a single case In a later publication, Brunner et al. (1993) reported that each of 5 affected males had a point mutation in the eighth exon of the MAOA structural gene, which changed a glutamine to a termination codon Caspi et al. (2002) studied a large sample of male children from birth to adulthood to determine why some children who are maltreated grow up to develop antisocial behavior, whereas others do not. Functional polymorphism in the MAOA gene was found to moderate the effect of maltreatment. Maltreated children with a genotype conferring high levels of MAOA expression were less likely to develop antisocial problems
