Maroteaux–Lamy syndrome
Maroteaux–Lamy , or mucopolysaccharidosis type VI (MPS-VI), is an inherited disease caused by a in the arylsulfatase B (ARSB). ARSB is responsible for the breakdown of large sugar molecules called glycosaminoglycans. In particular, ARSB breaks down dermatan sulfate and chondroitin sulfate. Because people with MPS-VI lack the ability to break down these GAGs, these chemicals build up in the lysosomes of cells. MPS-VI is therefore a type of storage disease.
