Abstract

OBJECTIVE: Recent research implicates the catechol-O-methyltransferase (COMT) ValMet polymorphism in stress sensitivity, through modulation of hypothalamic-pituitary-adrenal (HPA) function. In healthy samples, Met homozygosity has been associated with greater HPA activity (i.e., cortisol) and stress sensitivity, though findings are mixed among clinical samples. To date, there are no reports examining baseline or longitudinal changes in HPA activity as a function of COMT genotype in youth. This study tested the hypothesis that COMT genotype would be associated with cortisol secretion in normal and at-risk adolescents; specifically, that COMT genotype would be linked in a dose-response manner such that Met homozygotes would have the highest salivary cortisol levels, followed by heterozygotes, then Val homozygotes. In addition, this study examined the relation of COMT genotype with longitudinal changes in cortisol. METHODS: This study examined the association of COMT with salivary cortisol across a 1-year period in healthy and at-risk adolescents with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision Axis II diagnoses. RESULTS: Results indicated higher cortisol levels for Met homozygotes (compared with heterozygotes and Val homozygotes) at the 1-year follow-up, and increased mean cortisol levels across a 1-year period among Met carriers, suggesting that COMT associates with differences in cortisol secretion during adolescence. CONCLUSION: Findings are discussed with respect to COMT genotype as a potential genetic indicator of psychiatric risk that modulates developmental changes in HPA activity.

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.
