Mucopolysaccharidosis type I: molecular characteristics of two novel alpha-L-iduronidase mutations in Tunisian patients
BACKGROUND Mucopolysaccharidosis type I (MPS I) is an autosomal storage disease resulting from defective activity of the enzyme α-L-iduronidase (IDUA). This glycosidase is involved in the degradation of heparan sulfate and dermatan sulfate. MPS I has severe and milder phenotypic subtypes. AIM OF STUDY This study was carried out on six newly collected MPS I patients recruited from many regions...
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 کاملα-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 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 کاملmolecular detection and identification of α-l-iduronidase gene mutations in 5 iranian families suspected for muller syndrome (mucopolysaccharidosis i)
introduction: mucopolysaccharidosis i (mps-i) is an autosomal recessive lysosomal storage diseases, caused by α-l-iduronidase (idua) enzyme deficiency. the clinical manifestations of mps-i patients are variable ranging from severe to mild, and therefore prediction of disease severity is difficult. from when idua gene has been cloned more than 109 distinct mutations have been identified in it an...
