NCT01357707

Brief Summary

The project strives to discover novel genetic defects that cause monogenic epilepsy or that genetically modify a preexisting epileptic phenotype. Our main aim is to find genetic causes for the idiopathic West Syndrome (infantile seizures) that are not caused by known cerebral malformation, lissencephaly or metabolic disorders and which have a comparatively benign prognosis. The investigators hypothesize that mutations in genes coding for ion channels or genes that modify the action of ion channels might be causative. For that the investigators will perform a sequence analysis of the coding exons of a large set of genes in all recruited patients and verify found mutations in their parents.
