Seminal work from the laboratory of Dr. Rosco Brady defined the molecular basis of Types A, B and C Niemann-Pick disease (NPD), and paved the way for the development of the new therapies for these diseases. The demonstration that the enzyme acid sphingomyelinase (ASM) was deficient in patients with Types A and B NPD led to the first definitive diagnostic assays for this disorder, and the development of enzyme replacement therapy that is now being evaluated in clinical trials. This review will discuss the clinical, biochemical and molecular basis of Types A and B NPD, as well as the current status of therapy. The seminal contributions of Dr. Brady will be discussed.
