Juvenile myoclonic epilepsy (JME) also known as Janz syndrome is a fairly common form of idiopathic generalized epilepsy representing 5-10% of all epilepsies. This disorder typically first manifests itself between the ages of 12 and 18 with myoclonus occurring early in the morning. Most patients also have tonic-clonic seizures and many also have absence seizures. Linkage studies have demonstrated at least 6 loci for JME 4 with known causative genes.
