Abstract

Aggressive behaviors have become a major public health problem, and early-onset aggression can lead to outcomes such as substance abuse, antisocial personality disorder among other issues. In recent years, there has been an increase in research in the molecular and genetic underpinnings of aggressive behavior, and one of the candidate genes codes for the catechol-O-methyltransferase (COMT). COMT is involved in catabolizing catecholamines such as dopamine. These neurotransmitters appear to be involved in regulating mood which can contribute to aggression. The most common gene variant studied in the COMT gene is the Valine (Val) to Methionine (Met) substitution at codon 158. We will be reviewing the current literature on this gene variant in aggressive behavior.

  • The role of COMT in aggression was initially supported by observations of hostility in mice deficient in Comt and the negative correlation between COMT levels and hostility in men with behavioral problems as children.

    “The role of COMT in aggression was initially supported by observations of hostility in mice deficient in Comt and the negative correlation between COMT levels and hostility in men with behavioral problems as children [57, 58]; reviewed in Qayyum et al. (2015) [59].”

    From Genetics of child aggression, a systematic review (2024) · cites this paper as [59]

    The “COMT in Aggression” section reports enhanced fighting in male mice lacking one copy of comt and a negative correlation between COMT activity and hostility in men followed up after childhood hyperactivity. It supports the historical observations as a review, but the claim says COMT levels where the source specifies COMT activity. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
