Abstract

Deletion of the human SHANK3 gene near the terminus of chromosome 22q is associated with Phelan–McDermid syndrome and autism spectrum disorders. Nearly all such deletions also span the tightly linked IB2 gene. We show here that IB2 protein is broadly expressed in the brain and is highly enriched within postsynaptic densities. Experimental disruption of the IB2 gene in mice reduces AMPA and enhances NMDA receptor-mediated glutamatergic transmission in cerebellum, changes the morphology of Purkinje cell dendritic arbors, and induces motor and cognitive deficits suggesting an autism phenotype. These findings support a role for human IB2 mutation as a contributing genetic factor in Chr22qter-associated cognitive disorders.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Behavioral analyses of IB2 and Pax6 animal models indicate a possible link between these genes and autistic-like behavior.

    “Behavioral analyses of both IB2 and Pax6 animal models have also indicated a possible link between these genes and autistic-like behavior [277, 279].”
  • Specific deletion of IB2 in mice causes altered Purkinje cell morphology and disrupted cerebellar glutamatergic transmission.

    “Specific deletion of IB2 in mice results in altered Purkinje cell morphology and disruptions in cerebellar glutamatergic transmission [277].”

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.
