(A) Sphingomyelinase # Sphingomyelinase Converts Lipoproteins From Apolipoprotein> Deficiency, sphingomyelinase: Also called Niemann-Pick disease, this is a disorder of the metabolism of a lipid (fat) called sphingomyelin that usually causes the progressive development of enlargement of the liver and spleen (hepatosplenomegaly), "swollen glands" (lymphadenopathy), anemia and mental and physical deterioration.> Typical cells (called Niemann-Pick cells)that have a foamy appearance due to their storage of sphingomyelin are found in the bone marrow, spleen and lymph nodes.> Neurological features of Niemann-Pick disease include mental retardation, spasticity, seizures, jerks, eye paralysis (ophthalmoplegia) and ataxia (wobbliness).
