Abstract

Though different in their aetiology, autism spectrum disorder (ASD), Rett syndrome (RTT) and Down syndrome (DS) are three neurodevelopmental disorders sharing significant clinical and neuropathological overlaps. Genome-wide expression studies are reviewed and available datasets from post-mortem brains reanalyzed to identify genes and gene pathways dysregulated in all three disorders. Our results surprisingly converge upon immune, and not neurodevelopmental genes, as the most consistently shared abnormality in genome-wide expression patterns. A dysregulated immune response, accompanied by enhanced oxidative stress and abnormal mitochondrial metabolism seemingly represents the common molecular underpinning of these neurodevelopmental disorders. This conclusion may be important for the definition of pharmacological therapies able to ameliorate clinical symptoms across these disorders.

  • A model proposes that a dysregulated immune system leads to increased metabolism and reactive oxygen species pre- and postnatally, with prenatal changes in proliferation, migration, and neuronal wiring, and postnatal mitochondrial dysfunction and ROS stress leading to abnormal synaptic formation.

    “Lintas et al (2012) proposed a model whereby the dysregulated immune system leads to increased metabolism and reactive oxygen species (ROS) in both the pre-and postnatal environment.They suggest that such alterations would result in prenatal changes in proliferation, migration, and neuronal wiring, while postnatal mitochondrial dysfunction and ROS stress would lead to abnormal synaptic formation.”

  • In a review of genome-wide expression studies, of 464 genes identified, six of the top 10 KEGG ontology pathways were immune system functions.

    “When Lintas et al (2012) reviewed several genome-wide expression studies in 2012 (including the two just mentioned), they found a strong connection to the immune system; of the 464 genes identified, six out of the top 10 KEGG ontology pathways were functions of the immune systems.”

  • Immune dysregulation was a common trend in genomic studies, particularly in NK cell and cytokine pathways.

    “Immune dysregulation was a common trend in genomic studies, particularly in the NK cell and cytokine pathways.”

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.
