The unique case of the Niemann-Pick type C cholesterol storage disorder

Niemann-Pick type C disease (NPC) is a neurovisceral lysosomal cholesterol storage disorder that arises from loss-of-f unction mutations in either the NPCI or NPC2 genes. Both genes code for proteins involved in lysosomal cholesterol efflux. NPC is often diagnosed in early childhood, with patients typically displaying cerebellar ataxia, difficulties in Unfortunately, to date, there is no curative treatment for this devastating and fatal disorder, although several symptomatic manifestations of NPC are treatable. In this review, we discuss the cell biology of the disease, clinical aspects, diagnostic approaches, and current and potential therapeutic strategies against NPC.
