title: A new form of Niemann-Pick disease characterised by temperature-labile sphingomyelinase.
abstract: A new type (F) of Niemann-Pick disease characterised by childhood onset of splenomegaly, lack of neurological involvement, and diminished sphingomyelinase activity is described. The clinical presentation and heat-labile sphingomyelinase activity of this type F Niemann-Pick disease distinguishes it from other types of Niemann-Pick disease.
