New autism protein map offers path toward targeted treatments

Scientists have built the largest molecular map of autism ever created, and researchers in Cleveland say it could reshape how the condition is eventually treated.

Researchers at the University of California, San Francisco used artificial intelligence and lab-grown brain tissue to trace how more than 250 genes linked to autism spectrum disorder interact with each other inside the developing brain. The findings, published this week in the journal Science, identified more than 1,800 protein-to-protein interactions tied to autism — 87% of which had never been documented before.

The goal isn't to chase down a treatment for each individual gene. It's to find the shared biological pathways where many of those genes intersect, giving researchers a smaller set of targets that could potentially help far more people than any single-gene approach.

Dr. Matthew Anderson, co-director of the Oxford-Harrington Rare Disease Centre, a partnership between the University of Oxford and Harrington Discovery Institute at University Hospitals, and a professor at Case Western Reserve University, has worked on similar gene-mapping efforts himself dating back to 2017. He says the new study takes that same concept much further.

"You can puzzle it together and sort of get a sense of what's broken in different genetic forms of autism, and those become therapeutic targets," Anderson said. "Some of them may line up into the same pathways; that would mean you could use one therapy for multiple different genetic conditions."

Anderson noted that only an estimated 15%-25% of autism cases currently have an identifiable genetic cause using routine testing, meaning this map will most directly benefit that smaller group in the near term. He also pointed to a separate, growing body of research into inflammatory and immune-related changes seen in autism cases without a known genetic trigger — and said scientists are starting to see overlap between the two.

"There was a foundational line of research that already said that a pretty large percentage of cases of autism that didn't have a cause known had this inflammatory change in it," he told 3News. "There's convergence of the two — the genetic things will fall within pathways that align with the immune mechanisms that people think cause a larger proportion of autism."

Dr. Max Wiznitzer, a pediatric neurologist at UH Rainbow Babies and Children's Hospital, described the map as an important early step rather than a breakthrough patients will feel anytime soon.

"The map basically is a stepping stone. It's valuable because it shows relationships and it provides a direction in which to look," Wiznitzer said. "So it's valuable from the research standpoint, not yet from the clinical care standpoint."

Wiznitzer compared the disrupted brain networks seen in autism to a baseball team losing a key player.

"It doesn't disrupt only that player — it disrupts the entire team's performance," he said. "That's what this study is telling us: that it's networks that are being disrupted when you lose a key player, in this case a key gene and its function."

He cautioned that the findings may not apply equally to everyone diagnosed with autism, including those with more significant support needs, since a specific genetic cause is still identified in only a minority of cases. Any potential treatments would also need years of additional testing, starting in lab-grown brain organoids, before reaching human trials.

Outside the study, other autism researchers and advocacy groups called the findings a meaningful turning point. Alison Singer, president of the Autism Science Foundation, described it as "a huge watershed moment for autism science," while Dr. Andy Shih of Autism Speaks said the study offers valuable insight but that turning it into real therapies "is a long process."

For now, both Cleveland doctors agree the map gives researchers something they didn't have before: a clearer sense of where to look next.
