A large-scale study of KCNT1-related epilepsy involving 248 individuals showed that the epilepsy phenotypes caused by KCNT1 mutations primarily included early epilepsy of infancy with migrating focal seizures (EIMFS), developmental and epileptic encephalopathy other than EIMFS, ADSHE or sporadic SHE, temporal lobe epilepsy, and other types of epilepsy with tonic–clonic seizures (56, 57). The gene discussed is KCNT1; the disease is epilepsy.
