Ceroid Lipofuscinosis, Neuronal, 10, also known as neuronal ceroid lipofuscinosis due to cathepsin d deficiency, is related to lysosomal storage disease and peripheral retinal degeneration, and has symptoms including apnea, ataxia and muscle rigidity. An important gene associated with Ceroid Lipofuscinosis, Neuronal, 10 is CTSD (Cathepsin D). Affiliated tissues include brain and cortex, and related phenotypes are intracellular accumulation of autofluorescent lipopigment storage material and vascular granular osmiophilic material deposition
