N-Acetylgalactosamine-4-Sulfatase/N-Acetylgalactosamine-6-Sulfatase [Enzymatic activity ratio] in Urine
Arylsulfatase B/GALNS Ur-cRto
Definition
- The ratio of N-acetylgalactosamine 4-sulfatase to N-acetylgalactosamine 6-sulfatase helps differentiate between Morquio A syndrome and Maroteaux-Lamy syndrome. Morquio A syndrome (mucopolysaccharidosis type IVA) is associated with a deficiency of N-acetylgalactosamine 6-sulfatase, while Maroteaux-Lamy syndrome (mucopolysaccharidosis VI), is associated with a loss or decreased activity of N-acetylgalactosamine 4-sulfatase.
