Researchers at Princeton University and the Simons Foundation have identified four clinically and biologically distinct subtypes of autism, marking a transformative step in understanding the condition’s genetic underpinnings and potential for personalized care.
Analyzing data from over 5,000 children in SPARK, an autism cohort study, the researchers used a computational model to group individuals based on their combinations of traits.
The team used a “person-centered” approach that considered a broad range of over 230 traits in each individual, from social interactions to repetitive behaviors to developmental milestones, rather than searching for genetic links to single traits.
