Abstract

The P2RX7 gene (coding for P2X7 purinergic receptor) has been suggested as a novel candidate gene for major depressive disorder (MDD) and bipolar disorder (BPD). The proposed risk allele (G-allele) of the rs2230912 polymorphism results in an amino acid change at the 460th position, marking this genetic variation a possibly functional one. Here we present a case-control analysis of 171 patients diagnosed with MDD or BPD and 178 controls, as well as a dimensional approach using the Hospital Anxiety and Depression Scale (HADS) for studying the Gln460Arg polymorphism of the P2RX7 gene as a genetic risk factor in depression. While case-control analysis did not show significant difference between the groups, a significant association was found between the P2RX7 polymorphism and the HADS scales in the clinical group (MANOVA P = 0.001). Both anxiety and depression scores increased as the number of G-allele increased in the genotype groups (ANOVA for HADS-anxiety: P = 0.01, HADS-depression: P < 0.001). A significant interaction of clinical status and the P2RX7 polymorphism was also found for the depression scale (MANOVA P = 0.025, subsequent ANOVA for anxiety: P = 0.252; depression: P = 0.002). Whereas patients with G-allele-present genotypes showed more elevated depression scores, level of depression in the control group was not affected by the P2RX7 genotype. In conclusion, case-control analysis did not reveal significant results, but using a symptom severity scale we could support the association between depressive disorder and the G-allele of the Gln460Arg polymorphism in the P2RX7 gene.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In a case-control study, no difference in the presence of SNP rs2230912 between patients suffering from MDD and controls was shown.

    “Subsequent studies, however, have shown controversial results on this polymorphism, and in a case-control study no difference in the presence of SNP rs2230912 between patients suffering from MDD and controls was shown, although it was found that the severity of symptoms of depression was directly related to the presence of the polymorphism [72].”

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.
