Abstract

Genes overlap across psychiatric disease: Many genome-wide studies have examined genes associated with a range of neuropsychiatric disorders. However, the degree to which the genetic underpinnings of these diseases differ or overlap is unknown. Gandal et al. performed meta-analyses of transcriptomic studies covering five major psychiatric disorders and compared cases and controls to identify coexpressed gene modules. From this, they found that some psychiatric disorders share global gene expression patterns. This overlap in polygenic traits in neuropsychiatric disorders may allow for better diagnosis and treatment. Science , this issue p. 693

  • Virtually all cluster D modules failed to overlap with modules showing significant associations with neuropsychiatric disorders and were therefore "AD specific."

    “Interestingly, virtually all cluster D modules failed to overlap with modules showing significant associations with neuropsychiatric disorders (Figure S6A) and were therefore “AD specific.””

    From Meta-Analysis of the Alzheimer’s Disease Human Brain Transcriptome and Functional Dissection in Mouse Models (2020) · cites this paper as Gandal et al., 2018

    The indexed copy (section labeled Abstract; page unavailable) identifies co-expression modules significantly associated with psychiatric disorders, including CD4 and CD11. It does not examine the citing paper’s cluster D modules, test their overlap with those modules, or establish that they are AD-specific. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • AD consensus clusters B and C strongly overlapped with several neuropsychiatric coexpression modules similarly enriched for microglial and neuronal expression signatures.

    “In contrast, AD consensus clusters B and C strongly overlapped with several neuropsychiatric coexpression modules similarly enriched for microglial and neuronal expression signatures, respectively.”

    From Meta-Analysis of the Alzheimer’s Disease Human Brain Transcriptome and Functional Dissection in Mouse Models (2020) · cites this paper as Gandal et al., 2018

    The co-expression-module passage (section labeled Abstract; page unavailable) identifies a microglial-marker-enriched module, CD11, and neuronal modules, CD1, CD10, and CD13. It does not report AD consensus clusters B and C or test their overlap with those modules, so the claimed strong overlap is unsupported by this source. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Module CD11, which was increased in autism, overlapped significantly with AD cluster B module FPturquoise (padj = 1.3 × 10−136).

    “For example, module CD11, which was increased in autism, overlapped significantly with AD cluster B module FPturquoise (padj = 1.3 × 10−136) (Figure S6B).”

    From Meta-Analysis of the Alzheimer’s Disease Human Brain Transcriptome and Functional Dissection in Mouse Models (2020) · cites this paper as Gandal et al., 2018

    The paper’s passage on co-expression modules (indexed as Abstract; page unavailable) reports that CD11 was upregulated specifically in autism spectrum disorder. Our copy does not report an overlap with AD cluster B module FPturquoise or the adjusted P value of 1.3 × 10−136; searches for those terms found no supporting passage. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Genes expressed by microglia have been implicated in Alzheimer's disease in human GWASs.

    “Previously, genes expressed by microglia have been implicated in AD in human GWASs”

    From Cross-Species Single-Cell Analysis Reveals Divergence of the Primate Microglia Program (2019) · cites this paper as Gandal et al., 2018

    The indexed text describes a microglial gene module associated with autism and reports GWAS enrichment for other psychiatric disorders, but it does not link microglia-expressed genes to Alzheimer’s disease in human GWASs. Searches for “Alzheimer,” “AD GWAS,” and microglial Alzheimer’s risk variants found only an Alzheimer’s-related reference, not a passage making the claimed point; page numbers were unavailable. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Transcriptomic meta-analyses across major neuropsychiatric disorders found shared transcriptional dysregulation including a gradient of synaptic gene down-regulation and astroglial gene up-regulation in ASD, SZ and BD (ASD > SZ = BD), and dysregulation of HPA-axis and hormonal signaling in MDD.

    “Transcriptomic meta-analyses of human cerebral cortex across major neuropsychiatric disorders, including autism (ASD), schizophrenia (SZ), bipolar disorder (BD) and depression (MDD), have found the shared transcriptional dysregulation underlying convergent molecular neuropathology, such as a gradient of synaptic gene down-regulation and astroglial gene up-regulation in ASD, SZ and BD (ASD > SZ = B”

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.
