COMT Val158Met Genotype as a Risk Factor for Problem Behaviors in Youth

摘要

ObjectiveTo test the association between the catechol-O-methyltransferase (COMT) Val158Met polymorphism and both aggressive behavior and attention problems in youth. We hypothesized that youth carrying a Met allele would have greater average aggressive behavior scores, and youth exhibiting Val-homozygosity would have greater average attention problems scores.
