A study at Children's Hospital of Philadelphia and published in this month's Nature Genetics has proved significant, identifying gene variants associated with 10 percent of all ADHD cases, reports USA Today.
"Members of the GMR gene family, along with genes they interact with, affect nerve transmission, the formation of neurons, and interconnections in the brain, so the fact that children with ADHD are more likely to have alterations in these genes reinforces previous evidence that the GMR pathway is important in ADHD," study leader Dr. Hakon Hakonarson, director of the Center for Applied Genomics at Children's Hospital, said in the news release.
"Our findings get to the cause of the ADHD symptoms in a subset of children with the disease," he added.
