Description

Mutations in the SCN1A gene cause a spectrum of seizure disorders, ranging from early-onset isolated febrile seizures to generalized epilepsy with febrile seizures plus, type 2, which represents a more severe phenotype. Patients with isolated febrile seizures usually have onset between ages 6 months and 4 years and show spontaneous remission by age 6 years (summary by Mantegazza et al., 2005), whereas patients with GEFS+ continue to have various types of febrile and afebrile seizures later in life (summary by Singh et al., 2009). Dravet syndrome (OMIM ), or severe myoclonic epilepsy of infancy, is the most severe phenotype associated with SCN1A mutations.Mutations in certain genes can cause a phenotypic spectrum of overlap between the isolated febrile phenotype and the GEFS+ phenotype. For a general phenotypic description and a discussion of genetic heterogeneity of GEFS+, see {604233}. For a phenotypic description and a discussion of genetic heterogeneity of familial febrile seizures, see {121210}.
