The mucopolysaccharidoses (MPS) are a group of inherited disorders caused by specific enzyme deficiencies in the degradation of glycosaminoglycans. Glycosaminoglycans accumulate in lysosomes, and partially degraded glycosaminoglycans are excreted in urine. Clinical features depend on the specific enzyme deficiency, the organs affected, and the accumulation of glycosaminoglycans in the affected organs. Some of the enzyme deficiencies affect the brain, leading to mental retardation. The storage of glycosaminoglycans leads to coarse facial features and abnormalities in the connective tissue and bones. Currently, the MPS are subject for clinical trials using enzyme therapy.
