By mapping how distant genetic variants coordinate across six brain regions, a global team has identified 641 previously hidden schizophrenia risk genes — and shifted psychiatry closer to network-based precision treatments.
The Research
Researchers at the Lieber Institute for Brain Development, the University of Bari, and over 60 psychiatric hospitals worldwide analyzed genetic data from over 102,000 individuals alongside postmortem brain tissue samples from hundreds of donors, covering six distinct cortical regions. Instead of looking only at DNA variants next to a gene — what researchers call the “lamppost effect” — they built advanced computational models that capture long-range, network-wide regulatory relationships, similar to how social networks connect people who don’t live nearby. The study, published in Nature Genetics, uncovered 641 new risk genes that would have been missed by traditional methods. These genes cluster into biological pathways governing glutamate signaling, synaptic communication, immune responses, and early neurodevelopment.
“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, senior author. “By incorporating gene co-expression networks, we’ve essentially turned on lights across the entire neighborhood, revealing how distant genetic variants coordinate to build the genetic basis of schizophrenia.”
Why It Matters
For anyone curious about their own cognitive health, this research underscores an important principle: your brain’s function is not determined by isolated genes but by complex networks of genes working together. Understanding these coordinated programs can eventually lead to treatments tailored to an individual’s specific biological profile — precision psychiatry. In the meantime, it highlights how much of our cognitive risk and resilience is woven into the fabric of brain-wide gene communication.
What You Can Do
While you can’t change your genes, you can support your brain’s network health. Evidence-based habits like regular aerobic exercise, a Mediterranean diet rich in omega-3s, adequate sleep, and lifelong learning all promote neuroplasticity and may help maintain robust gene expression patterns.
