Scientists have discovered a genetic mutation linked to the human stress response that may be able to determine a person’s likelihood of committing suicide. They say they hope their discovery could lead to a simple blood test that would predict a person’s suicide risk.
A group of researchers from Johns Hopkins compared the brain tissue of people who had committed suicide to that of people without mental health problems, and found a key difference in a gene called SKA2.
The scientists then examined blood samples from three different groups of people who had been asked about whether they had thought about or attempted suicide, including one group of more than 300 people. They found the same genetic marker —

Yup this one worries me, a lot!
He stressed that a great deal more of research needs to be done to figure out what causes this particular expression of the SKA2 gene — he and his group don’t know whether people who committed suicide started out with that marker, or whether the SKA2 gene changed in response to something, such as elevated cortisol levels. “We really have a chicken or the egg problem” that needs to be examined further, he said.
