Genome-wide meta-analysis of depression identifies 102 independent variants and highlights the importance of the prefrontal brain regions
Open accessPublished version of a preprint
Abstract
Major depression is a debilitating psychiatric illness that is typically associated with low mood and anhedonia. Depression has a heritable component that has remained difficult to elucidate with current sample sizes due to the polygenic nature of the disorder. To maximize sample size, we meta-analyzed data on 807,553 individuals (246,363 cases and 561,190 controls) from the three largest genome-wide association studies of depression. We identified 102 independent variants, 269 genes, and 15 genesets associated with depression, including both genes and gene pathways associated with synaptic structure and neurotransmission. An enrichment analysis provided further evidence of the importance of prefrontal brain regions. In an independent replication sample of 1,306,354 individuals (414,055 cases and 892,299 controls), 87 of the 102 associated variants were significant after multiple testing correction. These findings advance our understanding of the complex genetic architecture of depression and provide several future avenues for understanding etiology and developing new treatment approaches. The authors conducted a genetic meta-analysis of depression and found 269 associated genes. These genes highlight several potential drug repositioning opportunities, and relationships with depression were found for neuroticism and smoking.

“Many of these genetic correlations are similar to those reported by Wray, et al. 9 and Howard, et al. 5, including earlier age at menarche (rG = -0.12, s.e = 0.02).”

- Partly supportedcites [9] Wray, N. R. et al. Genome-wide association analyses identify 44 risk variants and refine the genetic architecture of major depression. Nat. Genet. 50, 668–681 (2018). sourceExperimental — accuracy not yet measured
The Results section (“Implications based on relationships with other traits”; page not supplied) reports a genetic relationship between major depression and decreased age at menarche. The passages in our copy do not give the claimed rG of −0.12 or its standard error of 0.02, so the numerical part is not verified by this source. (LLM, conf=0.84)
- Partly supportedcites [5] Howard, D. M. et al. Genome-wide association study of depression phenotypes in UK Biobank identifies variants in excitatory synaptic pathways. Nat. Commun. 9, 1470 (2018). sourceExperimental — accuracy not yet measured
The Results section, “Genetic correlations with depression” (page unavailable), reports correlations between depression phenotypes and 235 other traits. The Discussion says some correlations were generally aligned with earlier reports. Our copy does not identify age at menarche or give the claimed rG of −0.12 (s.e. 0.02); searches for menarche and that value found no matching passage. (LLM, conf=0.77)

The authors state this as an assumption.
The analysis assumed normal distributions for all data without formally testing this.
“All data distributions were assumed to be normal but this was not formally tested.”
The authors state this as an assumption.
For Mendelian randomization, the instruments must be associated with the exposure.
“the genetic variants are associated with the exposure”
The authors state this as an assumption.
For Mendelian randomization, the instruments must not be associated with confounders of the exposure-outcome relationship.
“the genetic variants are independent of confounders in the exposure-outcome association”
The authors state this as an assumption.
For Mendelian randomization, the instruments must affect the outcome only through the exposure, without horizontal pleiotropy.
“the genetic variants are associated with the outcome only via their effect on the exposure, i.e. there is no horizontal pleiotropy whereby the variants affect both exposure and outcome independently.”
The paper relies on this without support.
Most antidepressant treatments work by interacting with the serotonergic system.
“This is surprising, as interaction with the serotonergic system forms the basis of most antidepressant treatments.”
The authors state this as an assumption.
The principal Mendelian randomization test (inverse-variance weighted regression) assumes a zero intercept.
“This method is based on a regression of the exposure and the outcome which assumes the intercept is constrained to zero”

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 2026-09-28, under version 3 of the claim definition (prompt extract-v3).
A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
