Abstract

Mutations in the postsynaptic scaffolding gene SHANK2 have recently been identified in individuals with autism spectrum disorder (ASD) and intellectual disability. However, the cellular and physiological consequences of these mutations in neurons remain unknown. We have analyzed the functional impact caused by two inherited and one de novo SHANK2 mutations from ASD individuals (L1008_P1009dup, T1127M, R462X). Although all three variants affect spine volume and have smaller SHANK2 cluster sizes, T1127M additionally fails to rescue spine volume in Shank2 knock-down neurons. R462X is not able to rescue spine volume and dendritic branching and lacks postsynaptic clustering, indicating the most severe dysfunction. To demonstrate that R462X when expressed in mouse can be linked to physiological effects, we analyzed synaptic transmission and behavior. Principal neurons of mice expressing rAAV-transduced SHANK2-R462X present a specific, long-lasting reduction in miniature postsynaptic AMPA receptor currents. This dominant negative effect translates into dose-dependent altered cognitive behavior of SHANK2-R462X-expressing mice, with an impact on the penetrance of ASD.

  • Human genetic studies indicate that SHANK1, SHANK2, and SHANK3 are causative genes for idiopathic autism spectrum disorders.

    “Recent human genetic studies indicate that SHANK family genes (SHANK1, SHANK2, and SHANK3) are causative genes for idiopathic autism spectrum disorders (ASD).”

    From Modeling Autism by SHANK Gene Mutations in Mice (2013) · cites this paper as Berkel et al., 2012

  • SHANK/ProSAP family proteins are promising candidates for modeling ASD in mice because of strong genetic evidence of SHANK molecular defects in ASD patients.

    “SHANK/ProSAP family proteins (SHANK1, SHANK2, SHANK3) have emerged as promising candidates for modeling ASD in mice due to strong genetic evidence showing molecular defects of SHANK in patients with ASD (Berkel et al., 2010; Berkel et al., 2012; Durand et al., 2007; Gauthier et al., 2010; Marshall et al., 2008; Pinto et al., 2010; Sato et al., 2012).”

  • Mutations in SHANK1 and SHANK2 have also been associated with ASD.

    “Recently, mutations in SHANK1 and SHANK2 have also been associated with ASD (Berkel et al., 2010; Berkel et al., 2012; Sato et al., 2012), supporting a general function for this gene family in common molecular pathways associated with ASD.”

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.
