Abstract

Much evidence of an association between specific attachment styles and depression prompted us to investigate, in depressive disorders, the potential role of polymorphisms within the gene encoding the receptor of the main neurohormone involved in attachment processes, oxytocin. For this purpose, two single nucleotide polymorphisms (SNPs), 6930G>A (rs53576) and 9073G>A (rs2254298), within the oxytocin receptor gene (OXTR), were studied in a cohort of 185 patients with major depression (50.3%) or bipolar I or II disorders (49.7%) and 192 matched healthy controls. A positive association between the GG genotype of OXTR SNPs (6930G>A or 9073G>A) and unipolar depression was demonstrated. In this group, GG individuals showed high scores on Attachment Style Questionnaire factors that have been previously associated with depression. Moreover, the GG genotype was also associated with high levels of adult separation anxiety. These findings support the involvement of the oxytocinergic system in the mechanisms that underlie depression and specific adult attachment styles.

  • Individuals homozygous for the G allele for SNPs rs53576 and rs2254298 exhibited higher scores on Attachment Style Questionnaire factors associated with depression and adult separation anxiety.

    “individuals homozygous for the G allele for the SNPS rs53576 and rs2254298 exhibited higher scores on Attachment Style Questionnaire factors that are associated with depression and adult separation anxiety (Costa et al., 2009).”

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.
