A buildup of rare versions of genes that control the activity of nerve cells in the brain increases a person’s risk for bipolar disorder, researchers suggest in a paper posted online the week of February 16 inProceedings of the National Academy of Sciences.

“There are many different variants in many different genes that contribute to the genetic risk,” says coauthor Jared Roach, a geneticist at the Institute for Systems Biology in Seattle. “We think that most people with bipolar disorder will have inherited several of these risk variants.
