A groundbreaking international study led by the Institute of Human Genetics at the University of Leipzig Medical Center has demonstrated that changes in a single gene can directly cause mental illness. This important finding challenges the previous assumption that mental disorders arise solely from a complex interplay of multiple genetic factors.

Published in the journal *Molecular Psychiatry*, the study provides new insights into the genetic basis of mental health conditions. By identifying a direct link between mutations in one specific gene and the development of mental illness, researchers hope to pave the way for more targeted treatments and improved diagnostic methods.

This discovery marks a significant advancement in the field of psychiatric genetics and could transform how mental disorders are understood and managed in the future.
