Niemann-Pick C research from mouse to gene

Abstract Understanding the molecular basis of Niemann–Pick C (NP-C) disease took decades of struggle. Here I describe our early efforts to unravel the complex lipid storage found in NP-C tissues, and how the mouse model for NP-C pointed us in the right direction. Our success in cloning the NP-C1 gene in 1997 can be attributed to collaboration between an international body of scientists and families coping with NP-C disease. The next challenge is to delineate the biological function of the NP-C1 protein.
