Description: A large Canadian family carries a clue that may lead to new treatments for epilepsy. Of the family's 14 members, eight have a common form of epilepsy: juvenile myoclonic epilepsy. All of the family members let a team from Montreal's McGill University study their DNA. Now the team, led by Guy A. Rouleau, MD, PhD, has found a mutant gene linked to the disease. They report their findings in the current issue of the journal Nature Genetics.
