Abstract

Autism spectrum disorder (ASD) is a complex developmental syndrome of unknown etiology. Recent studies employing exome- and genome-wide sequencing have identified nine high-confidence ASD (hcASD) genes. Working from the hypothesis that ASD-associated mutations in these biologically pleiotropic genes will disrupt intersecting developmental processes to contribute to a common phenotype, we have attempted to identify time periods, brain regions, and cell types in which these genes converge. We have constructed coexpression networks based on the hcASD "seed" genes, leveraging a rich expression data set encompassing multiple human brain regions across human development and into adulthood. By assessing enrichment of an independent set of probable ASD (pASD) genes, derived from the same sequencing studies, we demonstrate a key point of convergence in midfetal layer 5/6 cortical projection neurons. This approach informs when, where, and in what cell types mutations in these specific genes may be productively studied to clarify ASD pathophysiology.

  • Prior analyses have implicated excitatory glutamatergic neurons in the cortex and medium spiny neurons in the striatum in ASD.

    “Prior analyses have implicated excitatory glutamatergic neurons in the cortex and medium spiny neurons in the striatum in ASD (Chang et al., 2015; Parikshak et al., 2013; Willsey et al., 2013; Xu et al., 2014).”

    From Large-Scale Exome Sequencing Study Implicates Both Developmental and Functional Changes in the Neurobiology of Autism (2020) · cites this paper as Willsey et al., 2013

    The Results section, “Gene-Marker-Based Analysis Implicates Layer 5/6 Glutamatergic Projection Neurons in ASD” (page not provided), reports an ASD-associated signal in cortical glutamatergic projection neurons. The cited passages do not support the sentence’s additional claim about medium spiny neurons in the striatum. (LLM, conf=0.87)

  • ASD genes are expressed at high levels in the human cortex and early in development.

    “Thus, in keeping with prior analyses (Chang et al., 2015; Parikshak et al., 2013; Willsey et al., 2013; Xuet al., 2014), ASD genes are expressed at high levels in the human cortex and early in development.”

    From Large-Scale Exome Sequencing Study Implicates Both Developmental and Functional Changes in the Neurobiology of Autism (2020) · cites this paper as Willsey et al., 2013

    The Results section, “Expression Profiling Confirms the Expression of hcASD Genes in Midfetal Cortical Projection Neurons” (page unavailable), reports robust expression of five representative high-confidence ASD genes in human midfetal frontal-cortex projection neurons. This supports expression in the cortex early in development, but does not establish high expression levels for ASD genes generally across the human cortex. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Microarray probes for CHD8 do not perform well.

    “Because the microarray probes for CHD8 , one of the genes with the lowest p values for ASD association (De Rubeis et al., 2014), do not perform well (Willsey et al., 2013; Cotney et al., 2015)”

    From Large-Scale Exome Sequencing Study Implicates Both Developmental and Functional Changes in the Neurobiology of Autism (2020) · cites this paper as Willsey et al., 2013

    The Experimental Procedures section (Construction of Spatiotemporal Coexpression Networks; page unavailable) says CHD8 was an exception to the usual use of core microarray probes: its expression data came from the extended probe set. That supports unusual handling of CHD8 probes, but the paper does not say that the probes performed poorly or explain why the exception was made. (LLM, conf=0.75)

  • The PFC of individuals with ASD shows structural and functional changes, specifically in the ACC, oFC and lPFC.

    “It has been described that the PFC of individuals with ASD show structural and functional changes, specifically in the ACC, oFC and lPFC [367, 368].”

    From Development of prefrontal cortex (2022) · cites this paper as [367]

    The Introduction reports convergence of ASD risk genes in midfetal prefrontal cortical neurons, and the Results include orbitofrontal cortex in the analyzed PFC-MSC cluster. These passages support a link between prefrontal cortex and ASD, but they do not establish structural and functional changes in individuals with ASD, specifically in the ACC, oFC and lPFC. (LLM, conf=0.82)

  • Several studies have supported a nexus in mid-fetal, glutamatergic neurons during cortical development, with modestly divergent findings regarding deep versus superficial cortical layers.

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.
