Abstract

Autism spectrum disorder (ASD) is a markedly heterogeneous condition with a varied phenotypic presentation. Its high concordance among siblings, as well as its clear association with specific genetic disorders, both point to a strong genetic etiology. However, the molecular basis of ASD is still poorly understood, although recent studies point to the existence of sex‐specific ASD pathophysiologies and biomarkers. Despite this, little is known about how exactly sex influences the gene expression signatures of ASD probands. In an effort to identify sex‐dependent biomarkers and characterize their function, we present an analysis of a single paired‐end postmortem brain RNA‐Seq data set and a meta‐analysis of six blood‐based microarray data sets. Here, we identify several genes with sex‐dependent dysregulation, and many more with sex‐independent dysregulation. Moreover, through pathway analysis, we find that these sex‐independent biomarkers have substantially different biological roles than the sex‐dependent biomarkers, and that some of these pathways are ubiquitously dysregulated in both postmortem brain and blood. We conclude by synthesizing the discovered biomarker profiles with the extant literature, by highlighting the advantage of studying sex‐specific dysregulation directly, and by making a call for new transcriptomic data that comprise large female cohorts.

  • Evidence from animal and human studies suggests that endocrine-disrupting compounds such as bisphenol A affect neurodevelopmental outcomes via immune cell functioning, although most human studies are limited by imprecise measures of exposure.

    “Evidence from animal and human studies also suggests that endocrine-disrupting compounds such as bisphenol A affect neurodevelopmental outcomes via immune cell functioning274, although most human studies are limited by imprecise measures of exposure and more rigorous epidemiological studies are warranted275.”

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.
