question: Describe the genetic determinants of common epilepsies
answer: Genetic determinants of common epilepsies are defined as the interaction of mutations in one of two unlinked genes, SCN1 and SCN2, which code for the proteins hamartin and epilepticin, respectively. Disruption of these genes has been found to be associated with epileptic encephalopathies, but it is not entirely clear if this translates directly to the increased risk for epilepsy or via epigenetic changes.
