The lysosomal enzyme alpha-L-iduronidase (IDUA) hydrolyzes the nonreducing terminal iduronide glycosidic bond in heparan sulfate and dermatan sulfate (Scott et al. 1991). Defects in IDUA cause mucopolysaccharidosis type IH (MIM:607014, also called Hurler syndrome), mucopolysaccharidosis type IH/S (MIM:607015, also called HurlerScheie syndrome) and mucopolysaccharidosis type IS (MIM:607016, also called Scheie syndrome) (Scott et al. 1993).
