Abstract

Autism spectrum disorder (ASD) is a heterogeneous disease, but genetically defined models can provide an entry point to studying the molecular underpinnings of this disorder. We generated germline mutant mice with loss-of-function mutations in Chd8 , a de novo mutation strongly associated with ASD, and demonstrate that these mice display hallmark ASD behaviors, macrocephaly, and craniofacial abnormalities similar to patient phenotypes. Chd8 +/– mice display a broad, brain-region-specific dysregulation of major regulatory and cellular processes, most notably histone and chromatin modification, mRNA and protein processing, Wnt signaling, and cell-cycle regulation. We also find altered synaptic physiology in medium spiny neurons of the nucleus accumbens. Perturbation of Chd8 in adult mice recapitulates improved acquired motor learning behavior found in Chd8 +/– animals, suggesting a role for CHD8 in adult striatal circuits. These results support a mechanism linking chromatin modification to striatal dysfunction and the molecular pathology of ASD.

  • The Wnt signaling pathway plays a crucial role in neuronal progenitor proliferation and differentiation in the forebrain.

    “One of the risk genes, Chd8, encodes a protein that binds directly to β-catenin to recruit histone proteins and negatively regulates the Wnt signaling pathway, which plays a crucial role in neuronal progenitor proliferation and differentiation in the forebrain (39–42).”

  • Knock-down of the CHD8 ortholog results in macrocephaly in zebrafish and increased brain weight and volume in mice, phenotypes that reflect clinical observations in subjects with loss-of-function mutations in the gene.

    “Knock-down of the CHD8 ortholog results in macrocephaly in zebrafish [32, 343] and increased brain weight and volume [187, 287] in mice, phenotypes that reflect clinical observations in subjects with loss-of-function mutations in the gene [32].”

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.
