MAOA, maltreatment, and gene–environment interaction predicting children’s mental health: new evidence and a meta-analysis

Abstract

Previous research on adults has shown that a functional polymorphism in the promoter region of the monoamine oxidase A (MAOA) gene moderates the impact of childhood maltreatment on risk for developing antisocial behavior. Thus far, attempts to replicate this finding have been mixed. The current study (i) presents new data investigating this finding in a sample of 975 seven-year-old boys, and (ii) evaluates the extant data by conducting a meta-analysis of published findings. We replicated the original finding by showing that the MAOA polymorphism moderates the development of psychopathology after exposure to physical abuse, we extended the finding to childhood closer in time to the maltreatment experience, and we ruled-out the possibility of a spurious finding by accounting for passive and evocative gene-environment correlation. Moreover, meta-analysis demonstrated that across studies, the association between maltreatment and mental health problems is significantly stronger in the group of males with the genotype conferring low vs high MAOA activity. These findings provide the strongest evidence to date suggesting that the MAOA gene influences vulnerability to environmental stress, and that this biological process can be initiated early in life.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ELA effects are modified by genetics, child sex and/or gender, exposure features (e.g., timing, nature, and intensity), and the presence of other risks or protective factors.

    “Some observed modifiers of ELA effects include genetics [25, 87–89], child sex and/or gender [19, 90, 91], exposure features (e.g., timing, nature, and intensity) [21, 25], and the presence of other risks or protective factors [36].”
  • A genetic variation in the promoter region for the monoamine oxidase A gene (MAOA) increases antisocial behaviours in boys exposed to the stress of child abuse.

    “Similarly, a genetic variation in the promoter region for the monoamine oxidase A gene (MAOA) increases antisocial behaviours in boys exposed to the stress of child abuse127.”
  • Heterogeneity in adversity exposure in previous samples may explain why gene-by-environment associations have been inconsistently replicated.

    “In fact, heterogeneity in adversity exposure in previous samples may explain inconsistent replication of gene-by-environment associations (Kim-Cohen et al., 2006; Munafò et al., 2009).”
  • Kim-Cohen et al. (2006) found that the MAO-A polymorphism moderated the development of psychopathology after physical abuse in a sample of 975 seven-year-old boys.

    “For example, Kim-Cohen et al. (2006) found that the MAO-A polymorphism moderated the development of psychopathology after experiencing physical abuse in a sample of 975 seven-year-old boys.”

  • Only a few replications of the MAO-A finding have been published.

    “So far, there have only been a few replications of this important finding (Foley et al., 2004; Kim-Cohen et al., 2006; Nilsson et al., 2006).”

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.
