Six genes have be shown to influence the risk of developing psychopathy: ANKK1, DRD2, DRD4, MAOA, COMT, and 5-HTTLPR. Individual expression of psychopathy related phenotypes depend on which combination of alleles are inherited in addition to environmental factors.16 jun 2011

Is there a gene that makes you a psychopath?
Our results showed that expression levels of RPL109, ZNF132, CDH5, and OPRD1 genes in neurons explained 30–92% of the severity of psychopathy, and RPL109 expression was significantly associated with degree of psychopathy also in astrocytes.27 ago 2019
