The antisocial personality disorder (ASPD) is characterized by an incapacity for an individual to adapt himself or herself to the social norms. These social norms are extremely important because they govern many aspects of behavior during adolescence and adulthood. Patients with ASPD typically have irritability problems and aggressive feelings toward other people. These aggressive feelings toward other people are expressed in a context of threat and intimidation. The ASPD is less common in clinical settings comparing the total population, in which the prevalence is 1.1. The familial aggregation for ASPD has been registered, in which the 40-50% of the variance can be explained to genetic influences. Most of the studies of ASPD in molecular genetics have been applying the hypothesis of association of candidate genes, focusing on genes associated with neurotransmission pathways. This has been greatly relevant to the monoamine oxidase gene (MAO). Genes that promote specific behavior between individuals must have been selected through the process of natural selection. Aggressive behaviors and other types of behavior that have an evolutionary origin are similar in the fact that they have to be codified in the genes and will later be transmitted to their descendants.
