Disease:Defects in CLN8 are the cause of neuronal ceroid lipofuscinosis 8 (CLN8) [MIM:600143]. Childhood-onset neuronal ceroid lipofuscinoses (NCL) are a group of autosomal recessive progressive encephalopathies characterized by the accumulation of autofluorescent material, mainly ATP synthase subunit C, in various tissues, notably in neurons. Based on clinical features, the country of origin of patients, and the molecular genetic background of the disorder, at least seven different forms are thought to exist. CLN8 is characterized by normal early development, onset of generalized seizures between 5 and 10 years, and subsequent progressive mental retardation.,Disease:Defects in CLN8 are the cause of progressive epilepsy with mental retardation (EPMR) [MIM:610003]; also called Northern epilepsy variant of neuronal ceroid lipofuscinosis 8. EPMR is a form of NCL so far described only in Finland. It has been considered as a distinct clinical and genetic entity among the NCL.,online information:Neural Ceroid Lipofuscinoses mutation db,PTM:Does not seem to be N-glycosylated.,similarity:Contains 1 TLC (TRAM/LAG1/CLN8) domain.,
