Scientists at Boston University have found a gene that could help predict the risk of suicide and PTSD.
As they describe in their recent Molecular Psychiatry paper, the gene SKA2 tends to be “switched off” in the brains of people who die from suicide. The risk of suicide for Iraq and Afghanistan veterans is currently estimated to be 41 to 61 percent higher than in the general population.
A 2014 study in the Journal of Psychiatry was the first to make the link between suicide risk and SKA2 but only analyzed post-mortem brains. The Boston University study went a step further by looking at the status of SKA2 in the brains of living individuals thinking suicidal thoughts.
