Mucopolysaccharidosis I

A group of autosomal recessive lysosomal storage disorders caused by mutations in the gene encoding the enzyme, alpha-L-iduronidase (IDUA), required for the degradation of heparan and dermatan sulfates. This leads to abnormal accumulation of these glycosaminoglycans in various tissues causing a wide range of clinical presentations including cognitive and musculoskeletal disorders.
