What is niemann-pick syndrome?

Inherited disease. Niemann–pick is one of a group of fatal inherited metabolic disorders. This disease is a form of sphingolipidosis, as it involves defective metabolism of sphingolipids. Sphingolipidoses, in turn, are included in the larger family of lysosomal storage diseases (lsds). These accumulate in brain tissue and cause damage which eventually kills the victim. No current cure is known.
