Abstract

Schizophrenia is a highly heritable disorder. Genetic risk is conferred by a large number of alleles, including common alleles of small effect that might be detected by genome-wide association studies. Here we report a multi-stage schizophrenia genome-wide association study of up to 36,989 cases and 113,075 controls. We identify 128 independent associations spanning 108 conservatively defined loci that meet genome-wide significance, 83 of which have not been previously reported. Associations were enriched among genes expressed in brain, providing biological plausibility for the findings. Many findings have the potential to provide entirely new insights into aetiology, but associations at DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses. Independent of genes expressed in brain, associations were enriched among genes expressed in tissues that have important roles in immunity, providing support for the speculated link between the immune system and schizophrenia.

  • Conservative estimates are that 10-20% of people with ASD harbour a de novo rare point mutation or CNV contributing to their presentation.

    “Conservative estimates are that 10 -20% of people with ASD harbour a de novo rare point mutation or CNV contributing to their presentation (34, 49,50).”

    From Autism spectrum disorder (2020) · cites this paper as [50]

    The “Overlap with rare mutations” section discusses CNVs associated with ASD and genes with deleterious de novo mutations. It does not estimate that 10–20% of people with ASD carry such a variant or establish that those variants contribute to their individual presentations. No page number is available in our copy.

  • In ASD, a single de novo germ-line heterozygous loss-of-function point mutation can convey more risk than the cumulative effect of the top decile of polygenic risk for schizophrenia.

    “In ASD, a single de novo more risk than the cumulative effect of the top decile of polygenic risk for schizophrenia 47,50”

    From Autism spectrum disorder (2020) · cites this paper as [50]

    The Polygenic risk score profiling section reports that the highest schizophrenia risk-score decile had greater odds of affected status than the lowest decile. The Overlap with rare mutations section notes overlap with ASD-associated de novo mutations, but the paper does not estimate the risk from a single ASD loss-of-function mutation or compare it with the schizophrenia polygenic-risk decile. Page numbers are unavailable in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Large-scale GWAS have identified approximately 160 regions of the genome harboring common variants robustly associated with the diagnosis of schizophrenia, with evidence for a substantial polygenic component in signals that individually fall below genome-wide levels of significance.

    “Large-scale genome-wide association studies (GWAS) have identified approximately 160 regions of the genome harboring common variants robustly associated with the diagnosis of schizophrenia, with evidence for a substantial polygenic component in signals that individually fall below genome-wide levels of significance (Pardiñas et al., 2018; Ripke et al., 2014)”

  • Significant genetic correlations were found between ASD and schizophrenia (rG=0.211, p=1.03 x 10^-5) and educational attainment (rG=0.199, p=2.56 x 10^-9).

    “Significant correlations were found for several traits including schizophrenia 15 ( 𝑟 𝐺 = 0.211, p = 1.03 x 10 -5 ) and measures of cognitive ability, especially educational attainment 20 ( 𝑟 𝐺 = 0.199, p = 2.56 x 10 -9 )”

    From Identification of common genetic risk variants for autism spectrum disorder (2019) · cites this paper as [15]

    The “Overlap with rare mutations” section reports significant overlap between schizophrenia GWAS regions and genes with de novo mutations in ASD (P=0.035). It does not report the claimed genetic correlation (rG=0.211, p=1.03 × 10^-5). In the citing sentence, educational attainment has a separate citation, so that estimate is not attributed to this paper. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The scientific basis of the imbalance in PRS accuracy has been demonstrated theoretically, in simulations, and empirically across many traits and diseases.

    “The scientific basis of this imbalance has been demonstrated theoretically, in simulations, and empirically across many traits and diseases11–22.”

    From Clinical use of current polygenic risk scores may exacerbate health disparities (2019) · cites this paper as [18]

    The Polygenic risk score profiling section reports that schizophrenia risk-score prediction depends on the target sample, and it evaluates prediction in three samples. It does not demonstrate a theoretical or simulation-based explanation for an imbalance in PRS accuracy, or show that imbalance across many traits and diseases. (LLM, conf=0.79)

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.
