the secondary analysis of the population-based sample). No signal was detected for the main effect of antisocial features in the complete sample (males and females: N=4944, β=0.13, P=0.175; males only: N=2211, β=0.203, P=0.143). However, there was a modest signal for interaction between the risk environment and rs4714329 in males, but not in females, in the general population (males: a β of 0.647, and a P-value of 0.045 for the interaction term), and the risk allele G associated significantly with antisocial features among males with the childhood risk environment (N=636, β=0.68, P=0.012).
