A new Yale-led study suggests that autism may not be caused by one specific gene alone, but by how different autism-related genes affect the same brain pathways during development. Researchers found that many genes connected to autism appear to “converge,” meaning they disrupt similar processes in the brain as brain cells grow and mature.

This discovery is important because scientists have identified hundreds of genes linked to autism, making it difficult to understand why autism can look so different from person to person. By focusing on the shared pathways in the brain instead of individual genes, researchers hope future treatments and supports may become more targeted and effective.

The study also gives families hope that researchers are getting closer to understanding the biology of autism and how the brain develops differently in autistic individuals.
