What are MPS Diseases?
Mucopolysaccharidoses (MPS) are rare diseases related to limited enzyme production - lysosomal alpha-L-iduronidase - which leads to the buildup of complex carbohydrates in parts of the body. Several health problems are caused by the accumulation of these sugar molecules (mucopolysaccharides or glycosaminoglycans) in the heart, skeleton, eyes, joints, respiratory system, ears, and skin. There are nine types of MPS disorders.
How to diagnose?
This disorder is diagnosed through ECG, an x-ray of the spine, urine, and genetic testing. MPS disorders are also part of the newborn screening test, depending on the state, in the United States.
What is the treatment?
Currently, for certain types of MPS, patients have three options, enzyme replacement therapy, bone marrow, and hematopoietic stem cell transplant.
