Northern epilepsy is an autosomal recessive childhood onset epilepsy syndrome, clinically characterized by generalized tonic-clonic seizures with onset at 5 to 10 years of age and subsequent slowly progressive mental deterioration. The patients may reach 50 or 60 years of age. A mutation responsible for the disease has recently been identified in a novel gene on chromosome 8p23, encoding a putative membrane protein with an unknown function. The present study, based on three autopsied patients, is the first neuropathological analysis of the disease, and showed intraneuronal accumulation of cytoplasmic autofluorescent granules. The granules were strongly stained by the Luxol fast blue, periodic acid-Schiff, and Sudan black B methods in paraffin sections, and were immunoreactive for subunit c of the mitochondrial ATP synthase and sphingolipid activator proteins A and D. The intraneuronal storage was highly selective: the third layer of the isocortex and the hippocampal CA2, CA3, and CA4 sectors were severely affected, while other layers of the isocortex, the CA1 sector, and the cerebellar cortex were only minimally involved. The membrane-bound storage cytosomes showed a curvilinear ultrastructure with admixture of some granular components. Western blotting and N-terminal sequence analysis of purified storage material identified subunit c as the major component. These findings establish Northern epilepsy as a new form of neuronal ceroid-lipofuscinosis with an exceptionally protracted course.
