Influence of the COMT Genotype on Working Memory and Brain Activity Changes During Development
Abstract
Background The Valine158Methionine (Val158Met) polymorphism of the COMT gene leads to lower enzymatic activity and higher dopamine availability in Met carriers. The Met allele is associated with better performance and reduced prefrontal cortex activation during working memory (WM) tasks in adults. Dopaminergic system changes during adolescence may lead to a reduction of basal dopamine levels, potentially affecting Met allele benefits during development.Methods We investigated the association of COMT genotype with behavioral (n = 322) and magnetic resonance imaging data (n = 81-84) collected during performance of a visuospatial WM task and potential changes in these effects during development (reflected in age × genotype interactions). Data were collected from a cross-sectional and longitudinal typically developing sample of 6- to 20-year-olds.Results Visuospatial WM capacity exhibited an age × genotype interaction, with a benefit of the Met allele emerging after 10 years of age. There was a parallel age × genotype interaction on WM-related activation in the right inferior frontal gyrus and intraparietal sulcus (IPS), with increases in activation with age in the Val/Val group only. Main effects of COMT genotype were also observed in the IPS, with greater gray matter volumes bilaterally and greater right IPS activation in the Val/Val group compared with the Met carriers.Conclusions These results suggest that COMT genotype effects on WM brain activity and behavior are not static during development. The full developmental picture should be considered when trying to understand the impact of genetic polymorphisms on the mature cognition of healthy adult or psychiatric populations.

TL;DR
In a developmental sample, COMT Val158Met genotype effects on visuospatial working memory and related brain activity were not static: Met/Met individuals were poorer performers in childhood but became better performers from mid-adolescence, while Val/Val individuals showed age-related increases in right frontal and parietal activation. The authors interpret this as evidence that the adult pattern of COMT effects emerges during adolescence, possibly reflecting developmental decreases in basal dopamine.
Key findings
- Behavioral data (N=322, including 260 with longitudinal data) showed an age × genotype interaction: the Val dominance model improved fit over age/sex only (likelihood-ratio test, D=9.77, 4 df, p=.045), with a significant genotype × age⁻¹ interaction (F(1,500.1)=4.40, p=.036). Met/Met individuals switched from poorer performance in childhood to better performance from mid-adolescence, with model-estimated cross-over at 10.2 years.
- fMRI data (N=81, including 44 longitudinal) showed age × genotype interactions in right inferior frontal gyrus and right intraparietal sulcus/angular gyrus: activation increased with age in Val/Val participants only (parietal: F(1,22.5)=21.5, p<.001; frontal: F(1,20.3)=25.9, p<.001), while Met carriers showed no significant age effect (p>.2 and p>.4). The parietal cluster also showed greater activation in Val/Val than Met carriers.
- In-scanner performance was high but lower in WM than Control (accuracy 90.6% ± 10.6 vs. 98.4% ± 3.5, t(124)=9.52, p<.001; correct-trial RT 1277 ms ± 360 vs. 738 ms ± 215, t(124)=25.11, p<.001), with no main effect of genotype or age × genotype interaction on WM vs. Control performance (all ps > 0.29).
- VBM data (N=84, including 47 longitudinal) showed Met dominance clusters in bilateral lateral bank of the IPS, with greater gray matter volumes in Val/Val participants than Met carriers; the largest cluster showed only a weak trend for genotype × age, and genotype effects were greater in males than females bilaterally.
Methods
- Participants were from the Swedish “Brainchild” study, recruited by random sampling from the population registry in Nynäshamn; age groups were 6, 8, 10, 12, 14, 16, 18, 20, and 25 years. DNA was extracted from blood or saliva, and COMT rs4680 was genotyped.
- Visuospatial WM was assessed with the Dot Matrix task from the AWMA battery; behavioral analyses used linear mixed models with age transformations (age, age⁻¹, ln(age)), sex, COMT genotype, and interactions, comparing additive, Val dominance, and Met dominance models.
- MRI analyses used SPM5: fMRI WM–Control contrasts were analyzed with flexible factorial second-level models, and VBM gray matter data were processed with DARTEL and analyzed similarly, with FDR p<.05 and inclusive masking by the WM–Control main effect for fMRI.
Limitations
- The paper states that pubertal state was not evaluated, substance use was not recorded and could confound the age effect, and small age groups when split by sex plus lack of pubertal stage information prevented detailed investigation of sex differences during development.
- The paper notes that the fMRI task included only relatively low WM loads and a control task, whereas the behavioral score reflected performance up to each participant’s maximum WM load level; it also notes that the locations of gray matter effects differ across studies and that it remains unclear what greater parietal gray matter volumes in Val/Val individuals precisely reflect.
- The text also makes evident that the complicated non-independent design did not allow calculation of standardized effect statistics, and effect sizes from round 1 only are reported in supplementary information.

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.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
