It's great you're looking into the 2025 autism research!

A major theme was understanding autism as a spectrum with varied subtypes. Researchers identified 33 X-linked genetic variants related to brain development and reproducible subgroups with distinct genetics, biology, and behavior. This is leading to more targeted treatments.

There was also significant work done on gene-environment interactions, with the NIH funding $50 million for studies on environmental factors in autism.
