Preferred (foundation metadata concept)
A rare genetic epilepsy disorder with characteristics of autosomal dominant lesional and nonlesional focal epilepsy with variable penetrance. Focal seizures emanate from different cortical locations (temporal, frontal, centroparietal, parietal, parietal-occipital, occipital) in different family members, but for each individual a single focus remains constant throughout lifetime. Seizure type (tonic, tonic-clonic or hyperkinetic) and severity varies among family members and tends to decrease (but do not disappear) during adulthood.
