MeSH definition : A group of inherited metabolic disorders characterized by the intralysosomal accumulation
of SPHINGOLIPIDS primarily in the CENTRAL NERVOUS SYSTEM and to a variable degree
in the visceral organs. They are classified by the enzyme defect in the degradation
pathway and the substrate accumulation (or storage). Clinical features vary in subtypes
but neurodegeneration is a common sign.;
