June 24,2026: Scientists have discovered 641 previously unknown genes linked to schizophrenia, using a revolutionary method that maps how genes “talk” to each other across the brain, somewhat similar to how friends connect via the internet regardless of distance.
The study, published the journal Nature, analyzed genetic data from over 102,000 individuals and brain tissue samples from hundreds of donors across six different brain regions. The research was led by the Lieber Institute for Brain Development in Baltimore, in collaboration with the University of Bari, Italy, and more than 60 psychiatric hospitals worldwide.
For decades, researchers have known that schizophrenia runs in families, but finding the exact genes responsible has been like searching for needles in a haystack. Traditional methods only looked at DNA variants found close to genes.
“Most genetic studies have been looking for the light under the lamppost, focusing only on genes close to disease-associated DNA variants,” said Dr. Giulio Pergola, the study’s senior author and researcher at the Lieber Institute. “By incorporating gene co-expression networks, we’ve essentially turned on lights across the entire neighborhood.”
The new approach works like this: imagine genes as people in a city. Old methods only checked who lived next door. The new method uses advanced computer models to capture long-range regulatory relationships, similar to tracking how social media connects friends who live miles apart. This revealed how distant genetic variants coordinate to build the genetic basis of schizophrenia.
What they found, 641 brand news genes
The team identified 766 genes associated with schizophrenia at a stringent statistical threshold (PFDR < 0.01). Of these, 641 were previously unrecognized — genes that older methods completely missed because they sit far from the obvious DNA “danger zones.”
These genes point to specific biological pathways that go wrong in schizophrenia:
- Glutamate signaling — how brain cells use this key chemical messenger
- Brain-cell communication — the “wiring” between neurons
- Immune processes — the body’s defense system, increasingly linked to mental illness
- Brain development — how the brain builds itself from before birth
Toward “Precision Psychiatry”
“This work demonstrates that schizophrenia risk isn’t just about individual genes acting one after another — it’s about how networks of genes work together,” said Dr. Daniel Weinberger, CEO and Director of the Lieber Institute for Brain Development. “Understanding these coordinated genetic programs brings us closer to precision psychiatry, where treatments can be tailored to an individual’s specific biological profile.”
Schizophrenia affects approximately 1% of the global population — roughly 24 million people worldwide, according to the World Health Organization. It remains one of psychiatry’s most burdensome disorders, with current treatments often involving trial-and-error medication matching. This research could eventually help doctors predict which patients will respond to specific drugs based on their unique genetic “network fingerprint.”
Rather than targeting single genes with drugs, future therapies might aim to fix entire communication networks — potentially offering more effective and personalized care for millions of patients.
