Researchers Uncover New Cellular Pathway Behind Schizophrenia Risk

New study shows how a high-risk gene suppresses key brain chemical

Over the past few decades, researchers have identified more than 100 genes that may increase the risk of schizophrenia — a serious mental illness that can cause disordered thinking, delusions, and hallucinations. One of those genes is called neuregulin 3, and people with certain variations of this gene have an elevated risk of developing schizophrenia. But until recently, researchers weren’t sure exactly how neuregulin 3 influenced schizophrenia risk.
