Ceroid Lipofuscinosis Neuronal Protein 5 (CLN5)

CLN5 is one of eight which have been associated with neuronal ceroid lipofuscinoses (NCL). Also referred to as Batten disease, NCL comprises a class of autosomal recessive, neurodegenerative disorders affecting children. The genes responsible likely encode proteins involved in the degradation of post-translationally modified proteins in lysosomes. The primary defect in NCL disorders is thought to be associated with lysosomal storage function. The neuronal ceroid lipofuscinoses (CLN or NCL) are a group of autosomal recessive, progressive encephalopathies in children. They are characterized by psychomotor deterioration, visual failure, and the accumulation of autofluorescent lipopigment in neurons and other cell types.
