Interpretive Data

Mucopolysaccharides (Glycosaminoglycans) include:  Keratan Sulfate, Heparan Sulfate, Dermatan Sulfate, and Chondroitin Sulfates 4 and 6.  The excretion of Heparan Sulfate is variable.  A normal mucopolysaccharides screen does not exclude Sanfilippo Syndrome (Mucopolysaccharidosis Type III).
