Transcriptomic analysis in autism spectrum disorder suggests three molecular subtypes with distinct phenotypic profiles and functional pathways.

Abstract excerpt

Autism spectrum disorder (ASD) is highly heterogeneous. Molecular subtyping of ASD based on gene expression data will help address the biological heterogeneity of ASD. We analyze RNA-seq data from 1711 ASD samples, employing unsupervised non-negative matrix factorization (NMF) to identify subtypes, and characterize them with five categories: overall ASD symptoms, social-communication deficits,...
