LOINC display name : N-Acetylgalactosamine-4-Sulfatase/N-Acetylgalactosamine-6-Sulfatase (U) [Catalytic
ratio];
LOINC long common name : N-Acetylgalactosamine-4-Sulfatase/N-Acetylgalactosamine-6-Sulfatase [Enzymatic activity
ratio] in Urine;
LOINC short name : Arylsulfatase B/GALNS Ur-cRto;
LOINC description : 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.;
