α-L-iduronidase therapy for mucopolysaccharidosis type I
More than 500 patients with mucopolysaccharidosis type IH (MPS IH; Hurler syndrome) have been treated with hematopoietic cell transplantation (HCT) throughout the world since the introduction of transplantation as therapy almost 30 years ago. More recently, the availability of recombinant alpha-L-iduronidase (IDUA) has resulted in the widespread treatment of less severe forms of MPS I with enzy...
متن کاملThree novel α-L-iduronidase mutations in 10 unrelated Chinese mucopolysaccharidosis type I families
Mucopolysaccharidosis type I (MPS I) arises from a deficiency in the α-L-iduronidase (IDUA) enzyme. Although the clinical spectrum in MPS I patients is continuous, it was possible to recognize 3 phenotypes reflecting the severity of symptoms, viz., the Hurler, Scheie and Hurler/Scheie syndromes. In this study, 10 unrelated Chinese MPS I families (nine Hurler and one Hurler/Scheie) were investig...
متن کاملA novel p.E276K IDUA mutation decreasing α-L-iduronidase activity causes mucopolysaccharidosis type I
PURPOSE To characterize the pathogenic mutations causing mucopolysaccharidosis type I (MPS I) in two Thai patients: one with Hurler syndrome (MPS IH), the most severe form, and the other with Scheie syndrome (MPS IS), the mildest. Both presented with distinctive phenotype including corneal clouding. METHODS The entire coding regions of the α-L-iduronidase (IDUA) gene were amplified by PCR and...
متن کاملMesenchymal Stem Cells Do Not Prevent Antibody Responses against Human α-L-Iduronidase when Used to Treat Mucopolysaccharidosis Type I
Mucopolysaccharidosis type I (MPSI) is an autosomal recessive disease that leads to systemic lysosomal storage, which is caused by the absence of α-L-iduronidase (IDUA). Enzyme replacement therapy is recognized as the best therapeutic option for MPSI; however, high titers of anti-IDUA antibody have frequently been observed. Due to the immunosuppressant properties of MSC, we hypothesized that MS...
متن کاملInsights into Mucopolysaccharidosis I from the structure and action of α-L-Iduronidase
Mucopolysaccharidosis type I (MPS I), caused by mutations in the gene encoding α-L-iduronidase (IDUA), is one of approximately 70 genetic disorders collectively known as the lysosomal storage diseases. To gain insight into the basis for MPS I, we crystallized human IDUA produced in an Arabidopsis thaliana cgl mutant. IDUA consists of a TIM barrel domain containing the catalytic site, a β-sandwi...
