A rare genetic variant causing MAO-A deficiency has been associated with violent behavior in males.[12] In 2002 a study published by researchers at King's College London found a link between a genetic variant causing low levels of MAO-A and increased levels of antisocial behavior in people who had been mistreated as children.[13] An American group studying monkeys called MAO-A a "warrior gene" in 2004.[14] A 2008 study found a similar result involving the variant of the MAO-A gene, as well as the genes DAT1 and DRD2. In all three cases, the variants of these genes were associated with an elevated risk of violent and delinquent behavior, but only in people who experienced certain stresses during childhood
