Abstract

Although many genes predisposing to autism spectrum disorders (ASD) have been identified, the biological mechanism(s) remain unclear. Mouse models based on human disease-causing mutations provide the potential for understanding gene function and novel treatment development. Here, we characterize a mouse knockout of the Cntnap2 gene, which is strongly associated with ASD and allied neurodevelopmental disorders. Cntnap2(-/-) mice show deficits in the three core ASD behavioral domains, as well as hyperactivity and epileptic seizures, as have been reported in humans with CNTNAP2 mutations. Neuropathological and physiological analyses of these mice before the onset of seizures reveal neuronal migration abnormalities, reduced number of interneurons, and abnormal neuronal network activity. In addition, treatment with the FDA-approved drug risperidone ameliorates the targeted repetitive behaviors in the mutant mice. These data demonstrate a functional role for CNTNAP2 in brain development and provide a new tool for mechanistic and therapeutic research in ASD.

  • The time point of aberrant functional and structural connectivity coincides with the expression profile of the knockout genes, suggesting that the timing in which ASD risk genes are functionally active is critical for development of aberrant connectivity patterns and possibly behavioral symptoms later in life.

    “Interestingly, the time point of the aberrant functional and structural connectivity coincides with the expression profile of the knockout genes, suggesting that the timing in which ASD risk-genes are functionally active is critical for the development of aberrant connectivity patterns and possibly behavioral symptoms later in life.”
  • FMR1 plays a pivotal role in early embryotic neurodevelopment, whereas physiological expression of CNTNAP2 begins around E14 but peaks during adulthood at P56.

    “FMR1 plays a pivotal role in early embryotic neurodevelopment (Hinds et al. 1993) whereas the physiological expression of CNTNAP2 begins at around E14 but peaks during adulthood (P56) (Penagarikano et al. 2011).”
  • CNTNAP2-KO mice have a reduced number of GABAergic interneurons and impaired migration of cortical projection neurons.

    “CNTNAP2-KO mice have a reduced number of GABAergic interneurons and impaired migration of cortical projection neurons, which likely cause a higher incidence of seizures and abnormal behaviors such as impaired social interactions and elevated repetitive self-grooming (Penagarikano et al. 2011).”
  • Mice lacking Cntnap2 display deficits in social interaction and communication, hyperactivity, and seizures.

    “Mice lacking Contactin-associated protein 2 (Cntnap2) display deficits in social interaction and communication, hyperactivity, and seizures (Penagarikano et al., 2011).”

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.
