Niemann–Pick disease, type C as mitochondria, endoplasmic reticulum, plasma membrane, as well as early endocytic compartments has become one of the most interesting frontiers in neurondegenerative disease research including Alzheimer's disease, Parkinson's disease, as well as lysosomal storage disorders. Niemann–Pick disease, type C Niemann–Pick type C is a lysosomal storage disease associated with mutations in NPC1 and NPC2 genes. Niemann–Pick type C affects an estimated 1:150,000 people. Approximately 50% of cases present before 10 years of age, but manifestations may first be recognized as late as the sixth decade. Niemann–Pick type C has a wide clinical spectrum.
