A family of generalized epilepsy with febrile seizures plus type 2-a new missense mutation of SCN1A found in the pedigree of several patients with complex febrile seizures.
We report a family with complex febrile seizures (FS). The proband is a 15-year-old boy with seizures that persisted beyond 6 years of age. His father, aunt, and cousin also have the histories of FS until 8, 9, and 8 years old, respectively. A base substitution 5569G-->T of voltage-gated sodium channel alpha-1 subunit gene was found in DNA derived from the affected members of this family.
