A study published Wednesday in the JAMA Psychiatry journal shows that four key genetic variations are more common in military veterans who have taken their own life or considered it.

Scientists from Duke University in Durham, North Carolina, found the pattern while analyzing blood samples from a database that included 633,778 U.S. veterans, cross-referenced with the International Suicide Genetics Consortium of more than 549,000 individuals.

The obtained samples were sequenced to create genetic profiles compared to participants’ medical records, showing that 121,211 recorded cases of attempted suicide or thoughts about killing themselves.
