Abstract

Abstract Suicide accounts for nearly 800,000 deaths per year worldwide with rates of both deaths and attempts rising. Family studies have estimated substantial heritability of suicidal behavior; however, collecting the sample sizes necessary for successful genetic studies has remained a challenge. We utilized two different approaches in independent datasets to characterize the contribution of common genetic variation to suicide attempt. The first is a patient reported suicide attempt phenotype from genotyped samples in the UK Biobank (337,199 participants, 2,433 cases). The second leveraged electronic health record (EHR) data from the Vanderbilt University Medical Center (VUMC, 2.8 million patients, 3,250 cases) and machine learning to derive probabilities of attempting suicide in 24,546 genotyped patients. We identified significant and comparable heritability estimates of suicide attempt from both the patient reported phenotype in the UK Biobank (h 2 SNP = 0.035, p = 7.12×10 −4 ) and the clinically predicted phenotype from VUMC (h 2 SNP = 0.046, p = 1.51×10 −2 ). A significant genetic overlap was demonstrated between the two measures of suicide attempt in these independent samples through polygenic risk score analysis (t = 4.02, p = 5.75×10 −5 ) and genetic correlation (rg = 1.073, SE = 0.36, p = 0.003). Finally, we show significant but incomplete genetic correlation of suicide attempt with insomnia (rg = 0.34 - 0.81) as well as several psychiatric disorders (rg = 0.26 - 0.79). This work demonstrates the contribution of common genetic variation to suicide attempt. It points to a genetic underpinning to clinically predicted risk of attempting suicide that is similar to the genetic profile from a patient reported outcome. Lastly, it presents an approach for using EHR data and clinical prediction to generate quantitative measures from binary phenotypes that improved power for our genetic study.

  • Polygenic risk scores for depressive symptoms, neuroticism, major depressive disorder, and schizophrenia predicted suicide attempts in about 160,000 participants.

    “Ruderfer et al. found that PRS for depressive symptoms, neuroticism, major depressive disorder, and schizophrenia predicted suicide attempts in about 160,000 participants (41).”

    From Exploring the neurobiological markers of suicidal behaviors in pediatric population: a narrative review (2026) · cites this paper as [41]

    The Introduction (page unavailable) says more than 157,000 UK Biobank participants took the mental-health assessment, and the Results section on genetic correlation (page unavailable) reports positive genetic correlations between suicide attempt and all four named traits. But the paper does not report that polygenic risk scores for those four traits predicted attempts in about 160,000 participants. Its polygenic-risk-score analysis used a score derived from the UK Biobank suicide-attempt GWAS and tested it in 24,546 BioVU patients. (LLM, conf=0.88)

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.
