    ..Given that CHD8 is expressed predominantly during embryogenesis, it may thus contribute to setting a threshold for responsiveness to Wnt signaling that operates in a development-dependent manner. ..

    b>Duplin binds to beta-catenin and inhibits the Wnt signaling pathway, thereby leading to repression of the beta-catenin-mediated transactivation and Xenopus axis formation...

    ..Our results are thus consistent with the notion that CHD8 haploinsufficiency is a highly penetrant risk factor for ASD, with disease pathogenesis probably resulting from a delay in neurodevelopment. ..
