When examining children’s rule-breaking scores, we did not find a significant G×E interaction between MAOA genotype and TTES. Most other published studies examining this G×E interaction in children did not examine aggression and rule breaking as separate entities and instead looked at either conduct disorder or delinquency, which include elements of both aggression and rule breaking. To date, there is no consistent pattern of findings in the literature regarding the relationship among adversity, MAOA genotype, and rule-breaking behavior in children.
