About MPS I

The mucopolysaccharidoses (MPS) family is a group of inherited diseases, each caused by accumulation of various glycosaminoglycans (GAGs) in the lysosomes. The exact GAGs that accumulate are different in each case.

MPS diseases include seven sub-types: MPS I, MPS II, MPS III, MPS IV, MPS VI, MPS VII, and MPS IX. Mucopolysaccharidosis (MPS) can be as common as 1 in 25,000 live births.

MPS I is a rare genetic disorder that occurs in about 1 in every 100,000 births. Patients with MPS I disease can experience a wide range of symptoms with variable degrees of severity.
