Turns out, mental illness isn’t always about a bunch of tiny genetic tweaks—sometimes, it’s just one gene. Scientists found that knocking out the GRIN2A gene can single-handedly trigger early-onset psychiatric disorders like schizophrenia, anxiety, and mood swings, even in kids. The wild part? Some people improved with a simple supplement, L-serine. This could totally change how we diagnose and treat mental health, moving from vague labels to pinpointed, gene-based solutions. Mind. Blown. #Health #MentalHealth #Genetics
