Researchers recently discovered that a single gene GRIN2A can directly trigger mental illness, overturning decades of belief that psychiatric disorders always require many genes acting together. The study suggests that people with certain variants of this gene have a significantly higher risk of developing psychiatric symptoms.
Read the article to know why this breakthrough could change how mental illness is studied and treated worldwide.
