Study IDs Two Genes That Boost Risk for Post-Traumatic Stress Disorder

January 12, 2015

(Medical Xpress) – Why do some people develop post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA discovery may shed light on the answer. UCLA scientists have linked two gene variants to the debilitating mental disorder, suggesting that heredity influences a person’s risk of developing PTSD. Published in the February 2015 edition of the Journal of Affective Disorders, the findings could provide a biological basis for diagnosing and treating PTSD more effectively in the future.
