Interaction of dopamine transporter (DAT1) genotype and maltreatment for ADHD: a latent class analysis

Abstract

Background: Although the association of the dopamine transporter (DAT1) gene and attention‐deficit/hyperactivity disorder (ADHD) has been widely studied, far less is known about its potential interaction with environmental risk factors. Given that maltreatment is a replicated risk factor for ADHD, we explored the interaction between DAT1 and maltreatment with ADHD symptoms defined dimensionally and using latent class analysis (LCA). Method: We tested the association of the 40 base‐pair variable number of tandem repeats polymorphism in DAT1, maltreatment, and their interaction in 2,488 boys and girls from the National Longitudinal Study of Adolescent Health. Results: In boys, ADHD symptoms were optimally defined by four classes (Combined, Hyperactive/Impulsive, Inattentive, and Normal), whereas in girls, ADHD symptoms were defined by three classes (Combined, Combined‐Mild, Normal). A significant DAT1 × maltreatment interaction revealed that maltreated girls homozygous for the 10‐repeat allele had more symptoms of ADHD, and were also 2.5 times more likely to be classified in the Combined ADHD group than in the Normal Group. Conclusions: The underlying structure of ADHD symptoms differed between boys and girls and DAT1 interacted with maltreatment to predict ADHD symptoms and ADHD status derived from LCA. Interactive exchanges between maltreatment and DAT1 for ADHD symptoms, and their implications for intervention, are discussed.

  • Girls with the 10-10 repeat genotype within the dopamine transporter gene were significantly more likely to have problematic levels of ADHD following maltreatment than girls without this genotype.

    “In a study examining maltreatment of participants from AddHealth, girls with the 10-10 repeat genotype within the dopamine transporter gene were significantly more likely to have problematic levels of ADHD following maltreatment than girls without this genotype (Li and Lee, 2012).”

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.
