We examined the phenotypic variation and clinical genetics in nine families with generalized epilepsy with febrile seizures plus (GEFS+). This genetic epilepsy syndrome with heterogeneous phenotypes was hitherto described in only one family. We obtained genealogical information on 799 individuals and conducted detailed evaluation of 272 individuals. Ninety-one individuals had a history of seizures and 63 had epilepsy consistent with the GEFS+ syndrome. Epilepsy phenotypes were febrile seizures (FS) in 31, febrile seizures plus (FS+) in 15, FS+ with other seizure types (atonic, myoclonic, absence, or complex partial) in 8, and myoclonic-astatic epilepsy in 9 individuals. Inheritance was autos..
