AAP Grand Rounds 3:7-8 (2000) A New Genetic Marker for Febrile SeizuresSource: Peiffer A, Thompson J, Charlier C, et al. A locus for febrile seizures (FEB3) maps to chromosome 2q2324. Ann Neurol. 1999;46:671678.
The risk for febrile seizures has been previously shown to have a genetic component.1 To gain a better understanding of this association, linkage analysis genetic studies were conducted at the University of Utah in a four-generation family with 21 members affected by seizures associated with fever and inherited as an autosomal dominant trait. These seizures were generalized, tonic-clonic in pattern and they began between the ages of 5 months and 3 years (mean age, 1.3 years). They were recurrent in 18 patients, some having as many as 16 episodes, but none received antiepileptic medications and none had recurrences beyond 6 years of age (mean age, 4.1 years). Afebrile seizures of various types (generalized tonic-clonic, tonic, atonic, simple or complex partial
