Abstract

BACKGROUND: Oxytocin has been proposed to mediate amygdala dysfunction associated with altered emotion processing in schizophrenia, but the contribution of oxytocin pathway genes is yet to be investigated. AIMS: To identify potential different contributions of three oxytocin receptor polymorphisms (rs53576, rs237902 and rs2254298) between patients with schizophrenia spectrum disorders (SCZ), affective spectrum disorders (AD) and healthy controls (HC). METHOD: In a total of 346 participants (104 with SCZ, 100 with AD, and 142 HC) underwent genotyping and functional magnetic resonance imaging (fMRI) during an emotional faces matching paradigm. Genetic association analyses were performed to test the possible effects on task-induced BOLD amygdala response to fearful/angry faces. RESULTS: =0.03). There were no associations between oxytocin polymorphisms and amygdala activation in the total sample, among AD patients or HC. CONCLUSIONS: Rs237902 was associated with amygdala activation in response to fearful/angry faces only in patients with SCZ. Our findings indicate that the endogenous oxytocin system could serve as a contributing factor in biological underpinnings of emotion processing and that this contribution is disorder specific.

  • In humans, alterations in amygdala responses to positive and negative emotions have been reported in neuropsychiatric conditions such as autism and schizophrenia, in association with OXTR genetic variants or following intranasal OXT.

    “In humans, alterations in amygdala responses to positive and negative emotions have been reported in neuropsychiatric conditions, such as autism and schizophrenia [72,73], in association with OXTR genetic variants [41,102] or following intranasal OXT [33,36,38,103].”

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.
