WASHINGTON (Reuters) - Two genes that influence the activity of nerve cells in the brain may play a key role in a person's risk for bipolar disorder, marked by dramatic swings from depression to manic behavior, researchers said on Sunday. The findings are not expected to lead to a genetic test for the risk of the condition but could help unravel the mystery of how it arises and lead to better treatments, they reported in the journal Nature Genetics.
