Bi-Polar Suicide Risk

"Researchers at Johns Hopkins university say they've identified a gene variant that makes people with bipolar disorder more likely to attempt suicide.

The scientists looked at DNA from about 2,700 people with bipolar disorder where about half had attempted suicide and half had not. They found that the people whose DNA had a particular gene variant were from 1.4 to 3 times as likely to have attempted suicide, depending on how many copies of the variant were present. Studying additional DNA from over 3,000 more people with bipolar disorder confirmed these findings."
