Gene for depression identified

SCIENTISTS have identified a gene associated with major depression, potentially paving the way for a novel class of anti-depressant medication.

The discovery was made by German scientists who compared DNA from more than 15,000 depressed and healthy patients.

Altered letters in the genetic code were identified that were clearly associated with depression, researchers said, and they appeared to influence a gene called SLC6A15, which is believed to regulate glutamate in the brain.
