Abstract

The underlying genetic causes of idiopathic generalised epilepsies (IGE) are still largely unknown. In an animal model of IGE we have discovered novel genetic abnormalities an ion channel. This proposal will build upon these novel findings to examine the role these abnormalities have in determining the absence epilepsy phenotype and this work has the potential to provide vital information regarding the mechanisms by which this gene contributes to an IGE seizure phenotype.
