Lack of SCN1A mutations in familial febrile seizures.

Purpose: Mutations in the voltage-gated sodium channel subunit gene SCN1A have been associated with febrile seizures (FSs) in autosomal dominant generalized epilepsy with febrile seizures plus (GEFS+) families and severe myoclonic epilepsy of infancy. The present study assessed the role of SCN1A in familial typical FSs.

Methods: FS families were selected throughout a collaborative study of the Italian League Against Epilepsy.
