Following DM exposure, the mutant mice displayed an exacerbated phenotype in the elevated plus maze, and genes associated with vascular endothelial cells were downregulated in the cerebral cortex of older Chd8 animals. Our study reveals a gene x environment interaction with a Chd8 haploinsufficient mouse line and points to the importance of investigating phenotypes in ASD animal models across the lifespan.

Importantly, in addition to ataxia phenotype, mice with GNP-specific Chd8 ablation present a neuropsychiatric phenotype in three-chamber and light/dark tests. Taken together, our results provide insights not only into the function of CHD8 in cerebellar development, but also the pathogenesis of neuropsychiatric disorders in patients with CHD8 mutations.

CHD8 (Chromodomain Helicase DNA Binding Protein 8)
In addition, phagocytosis activity was inhibited by Tsc2 deficiency, microglia-mediated oligodendrocyte development was inhibited, in particular, the differentiation of oligodendrocyte precursor cells to oligodendrocytes was prevented by Chd8 or Tsc2 deficiency. These results suggest that ASD-related gene expression in microglia is involved in oligodendrocyte differentiation, which may contribute to the white matter pathology relating to ASD.
