Aims

Epilepsy with auditory features (EAF) is a focal epilepsy syndrome characterized by prominent auditory ictal manifestations. Two main genes, LGI1 and RELN, have been implicated in EAF, but the genetic aetiology remains unknown in half of families and most sporadic cases. We previously described a pathogenic SCN1A missense variant (p.Thr956Met) segregating in a large family in which the proband and her affected daughter had EAF, thus satisfying the minimum requirement for diagnosis of autosomal dominant EAF (ADEAF). However, the remaining eight affected family members had clinical manifestations typically found in families with genetic epilepsy with febrile seizures plus (GEFS+). We aimed to investigate the role/impact of SCN1A mutations in EAF.
