Information
When the body cannot break down mucopolysaccharides, a condition called mucopolysaccharidoses (MPS) occurs. MPS refers to a group of inherited disorders of metabolism. People with MPS do not have any, or enough of a substance (enzyme
) needed to break down the sugar molecule chains.
Forms of MPS include:
These conditions cause mucopolysaccharides to build up in body tissues. This can damage organs, including the heart. Symptoms can range from mild to severe and may include:
- Abnormal features of the face
- Bone, cartilage, and connective tissue deformities
-
Mental retardation
