A study published in The Lancet found four genetic markers associated with autism, attention-deficit/hyperactivity disorder, schizophrenia, bipolar disorder and major depression. Of these gene variants, researchers said two help regulate calcium levels in brain cells. While detecting these genes is not enough to predict a person's risk for psychiatric disorders, the findings offer a better understanding of the conditions, lead researcher Dr. Jordan Smoller said.
