MPS Diseases Information

Information to assist families and their communities

Mucopolysaccharidoses (MPS) and mucolipidosis (ML) are genetic lysosomal storage diseases (LSD) caused by the body’s inability to produce specific enzymes. The missing or insufficient enzyme prevents cells from recycling waste, resulting in the storage of materials in cells throughout the body. As the disease progresses, there is widespread damage throughout the body, including the heart, bones, joints, respiratory system and central nervous system, leading to a shortened lifespan.
