MAOA-uVNTR results in differential enzyme activity, so that high-activity alleles (MAOA-H) are linked to reduced dopamine, serotonin, and norepinephrine availability in comparison to low-activity allele (MAOA-L). As MAOA-uVNTR has been previously described to moderate the relationship between childhood parental maltreatment and aggressive and antisocial behavior, it may also play a role in CU traits etiology.9 p.application/pdfengcc-by-nc (c) Pueyo, N. et al., 2021https://creativecommons.org/licenses/by-nc/4.0/AminesTrastorns de la conducta en els infantsAminesBehavior disorders in childreninfo:eu-repo/semantics/article7171722022-03-10info:eu-repo/semantics/openAccess
