Niemann-Pick disease (NPD) types A and B (and A/B) are also known as acid sphingomyelinase deficiency (ASMD), and these are rare progressive genetic disorders that are potentially life threatening. ASMD results from a deficiency of an enzyme called acid sphingomyelinase, also known as ASM enzyme, which is required to metabolize a fatty substance called sphingomyelin. When the body is unable to make enough ASM enzymes, sphingomyelin cannot be broken down efficiently, which leads to a buildup...
