Overlooked DNA regions shed light on the genetic puzzle of autism spectrum disorder - University of Toronto

A study led by researchers at the University of Toronto identified hundreds of new microexons linked to autism spectrum disorder (ASD) and other neurological conditions, highlighting their role in brain-specific processes. Using a machine learning model, the team found that rare genetic variants significantly impact the regulation of these microexons, offering new insights into the genetic basis of ASD. The research suggests that overlooked DNA regions, particularly those involving microexons, may explain a large portion of the missing genetic factors in ASD.
