Abnormal expression of genes in psychopathy

Psychopathy is associated with altered expression of genes and immune responses related to molecular pathways. In neurons, the up-regulation of PRL10P9 and ZNF132 and down-regulation of CDG5 and OPRD1 were linked to psychopathic behaviors. The genetic expression explained up to 92% of the variance of psychopathic symptoms. Researchers speculated these genes may be relevant to the lack of empathy and emotional callousness associated with psychopathy, as previous studies have linked a number of these genes to ASD and problematic social behaviors.
