We review hereditary influences in the epilepsies from the perspective of medical genetics. The recurrence risk for epilepsy in close relatives may vary from 2% to 5% up to 50% depending on the etiology of the seizure disorder in the proband. We emphasize the identification of specific disorders with single-gene inheritance that will lead to useful conclusions regarding treatment, prognosis, and family counseling. Also discussed are chromosomal aberrations, polygenic inheritance, gene-environment interactions, animal models of epilepsy, and the pharmacogenetics of anticonvulsants.
