Duplication of the autism-related gene Chd8 leads to behavioral hyperactivity and neurodevelopmental defects in mice.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Mutations in the gene encoding chromodomain helicase DNA-binding protein 8 (CHD8) are strongly associated with autism spectrum disorder (ASD). Although duplications of the chromosomal locus including CHD8 have also been detected in individuals with neurodevelopmental disorders, the contribution of CHD8 duplication to clinical phenotypes and the underlying mechanisms have remained unknown. Here we show that Chd8 knock-in (KI) mice that overexpress CHD8 as a model of human CHD8 duplication manifest growth retardation, microcephaly, impaired neuronal differentiation, and behavioral abnormalities including hyperactivity and reduced anxiety-like behavior. Chd8 overexpression affects the transcription and chromatin accessibility of genes related to neurogenesis, with these changes being associated with aberrant binding of CHD8 to enhancer regions. Furthermore, pharmacological intervention partially ameliorates the hyperactivity of Chd8 KI mice. Our results thus indicate that Chd8 KI mice recapitulate key features of CHD8 duplication syndrome in humans, providing insight into pathogenic mechanisms underlying neurodevelopmental disorders.
