Gene associated with suicide risk

This article talks about a study identifying a gene associated with higher risks of suicide in depressed patients.

John Mann of the New York State Psychiatric Institute claims that in a sample of depressed patients, those who attempted suicide are more likely to have two copies of a particular allele at the RGS2 gene. This could suggest that the risk of suicide in depressed patients is inheritable, and it could explain why there are clusters of suicide attempts in families such as the Hemingway family (pictured).
