Abstract

Increased risk for autism spectrum disorders (ASD) is attributed to hundreds of genetic loci. The convergence of ASD variants have been investigated using various approaches, including protein interactions extracted from the published literature. However, these datasets are frequently incomplete, carry biases and are limited to interactions of a single splicing isoform, which may not be expressed in the disease-relevant tissue. Here we introduce a new interactome mapping approach by experimentally identifying interactions between brain-expressed alternatively spliced variants of ASD risk factors. The Autism Spliceform Interaction Network reveals that almost half of the detected interactions and about 30% of the newly identified interacting partners represent contribution from splicing variants, emphasizing the importance of isoform networks. Isoform interactions greatly contribute to establishing direct physical connections between proteins from the de novo autism CNVs. Our findings demonstrate the critical role of spliceform networks for translating genetic knowledge into a better understanding of human diseases. Autism spectrum disorder (ASD) is a complex genetic trait that encompasses a range of neurodevelopmental disorders. Here, the authors clone brain-expressed alternatively-spliced isoforms of ASD risk factors and construct a network of protein interactions that provides further insight into the disease aetiology.

  • Genes within ASD CNVs are highly connected with each other and with other ASD genes.

    “Studies of large CNVs in ASD have shown that genes within ASD CNVs are highly connected with each other (Corominas et al., 2014) and with other ASD genes (Pinto et al., 2014).”

  • The results suggest that misregulation of microexons, and of longer alternative exons, may affect protein interaction networks needed for normal neuronal development and synaptic function.

    “the results suggest that the misregulation of microexons, as well as of longer alternative exons (Corominas et al., 2014; Voineagu et al., 2011), may impact protein interaction networks that are required for normal neuronal development and synaptic function”

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.
