    Abstract:
    SCN1A is the most clinically relevant epilepsy gene and is associated with generalized epilepsy and febrile seizure plus (GEFS+) and Dravet syndrome. We postulated that earlier onset of febrile seizures in the febrile seizure (FS) and febrile seizure plus (FS+) phenotypes may occur in the presence of a SCN1A mutation. This was because of the age-related onset of Dravet syndrome, which typically begins in the first year of life. We found that patients with FS and FS+ with SCN1A mutations had earlier median onset of febrile seizures compared to the population median. Patients with GABRG2 mutations had a similar early onset in contrast to patients with SCN1B mutations where onset was later. This study is the first to demonstrate that a specific genetic abnormality directly influences the FS and FS+ phenotype in terms of age of onset.
