Mapping genes in juvenile myoclonic epilepsy.

The genetics of the various forms of epilepsy can be best understood by knowing where the affected gene is located. Genetic methodologies used to explore the genetics of epilepsy now include segregation analysis, linkage analysis and recombinant DNA technology. Juvenile myoclonic epilepsy (JME), a form of idiopathic epilepsy with a strong genetic component, provides informative pedigrees for linkage studies. Preliminary results demonstrate the heterogenous nature of the JME syndrome.
