NOS= Not otherwise specified; LRE=Localiization related epilepsy; BECTS=Benign epilepsy with centrotemporal spikes; cTLE=cryptogenic TLE; cryp=cryptogenic; symp=symptomatic; GE=generalized epilepsy; IGE=idiopathic generalized epilepsy; CAE=Childhood absence epilepsy; JAE=Juvenile absence epilepsy; JME=Juvenile myoclonic epilepsy; GTC=Generalized tonic-clonic seizure.

^*Individuals with isolated unprovoked seizures were enrolled in EPGP if they had epileptiform EEG abnormalities. The single individual with an isolated unprovoked seizure had a generalized epileptiform EEG abnormality and was therefore coded as GE in our analyses.
