Abstract

We performed a comprehensive assessment of rare inherited variation in autism spectrum disorder (ASD) by analyzing whole-genome sequences of 2,308 individuals from families with multiple affected children. We implicate 69 genes in ASD risk, including 24 passing genome-wide Bonferroni correction and 16 new ASD risk genes, most supported by rare inherited variants, a substantial extension of previous findings. Biological pathways enriched for genes harboring inherited variants represent cytoskeletal organization and ion transport, which are distinct from pathways implicated in previous studies. Nevertheless, the de novo and inherited genes contribute to a common protein-protein interaction network. We also identified structural variants (SVs) affecting non-coding regions, implicating recurrent deletions in the promoters of DLG2 and NR3C2. Loss of nr3c2 function in zebrafish disrupts sleep and social function, overlapping with human ASD-related phenotypes. These data support the utility of studying multiplex families in ASD and are available through the Hartwell Autism Research and Technology portal.

  • These results are consistent with previous studies in post-mortem brain that identified dysregulation of gene expression in microglia but enriched expression of ASD risk genes only in neuronal cells.

    “These results are consistent with previous studies in post-mortem brain that identified dysregulation of gene expression in microglia but enriched expression of ASD risk genes only in neuronal cells (Ruzzo et al., 2019; Gandal et al., 2018a, 2018b; Voineagu et al., 2011).”

    From Large-Scale Exome Sequencing Study Implicates Both Developmental and Functional Changes in the Neurobiology of Autism (2020) · cites this paper as Ruzzo et al., 2019

    The Results section (“Biological insights from known and novel ASD genes”; page not provided) reports enrichment of ASD-risk genes in mid-gestation and adult glutamatergic projection neurons. It does not report microglial gene-expression dysregulation in post-mortem brain or establish that enrichment occurs only in neuronal cells. (LLM, conf=0.86)

  • An analysis of genome sequencing data from 2,308 individuals in 493 multiplex ASD families from the Autism Genetic Resource Exchange conducted through TADA mega-analysis identified NCKAP1 among 69 genes associated with an ASD risk.

    “An analysis of genome sequencing data from 2,308 individuals in 493 multiplex ASD families from the Autism Genetic Resource Exchange (AGRE) conducted through TADA (Transmitted And De novo Association) mega-analysis identified NCKAP1 among 69 genes associated with an ASD risk128.”

    From The WAVE complex in developmental and adulthood brain disorders (2025) · cites this paper as [128]

    The Results section reports whole-genome sequencing of 2,308 individuals in 493 AGRE multiplex ASD families and identifies 69 ASD-associated genes in a TADA mega-analysis. Our copy does not identify NCKAP1 as one of those genes. The Methods also clarify that the mega-analysis combined the AGRE cohort’s variants with data from other cohorts, rather than analyzing only the 2,308 individuals. (LLM, conf=0.85)

  • Previous work indicates neurons as the central cell type harboring genetic risk for the majority of psychiatric disorders.

    “In contrast to AD in which multiple glial cells are implicated, previous work has indicated neurons as the central cell-type harboring genetic risk for the majority of psychiatric disorders3,22,46,58–61.”

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.
