Autism study reveals four biological subtypes

A major study has identified four distinct biological subtypes of autism, potentially revolutionizing diagnosis and treatment by enabling precision care. This research marks a significant step toward understanding the genetic basis of the condition. Researchers analyzed data from over 5,000 children, identifying subtypes based on a wide range of traits. These subtypes, linked to distinct genetic profiles and developmental trajectories, include Social and Behavioral Challenges, Mixed ASD with Developmental Delay, Moderate Challenges, and Broadly Affected. The findings, published in Nature Genetics, offer a new framework for understanding autism's complexity. This could lead to earlier diagnoses, tailored treatments, and a better understanding of the condition's diverse presentations and underlying biology.
