Generalized Epilepsy With Febrile Seizures Plus, Type 3; Gefsp3

Description

Mutations in the GABRG2 gene cause a spectrum of seizure disorders, ranging from early-onset isolated febrile seizures to generalized epilepsy with febrile seizures plus, type 3, which represents a more severe phenotype. Patients with isolated febrile seizures usually have onset in the first year of life and show spontaneous remission by age 6 years, whereas patients with GEFS+ continue to have various types of febrile and afebrile seizures later in life (summary by Singh et al., 1999). Mutation in the GABRG2 gene can also cause childhood absence epilepsy (ECA2 ).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}.
