Mucopolysaccharidoses (MPS) are rare lysosomal disorders caused by the deficiency of specific lysosomal enzymes responsible for glycosaminoglycan (GAG) degradation. Enzyme Replacement Therapy (ERT) has been shown to reduce accumulation and urinary excretion of GAG, and to improve some of the patients' clinical signs. We studied biochemical and molecular characteristics of nine MPS patients (two...
Mucopolysaccharidosis type VI (MPS VI) is an autosomal recessive disease caused by a deficiency of N-acetylgalactosamine 4-sulfatase (4S) leading to the lysosomal accumulation and urinary excretion of dermatan sulfate. MPS VI has also been described in the Siamese cat. As an initial step toward enzyme replacement therapy with recombinant feline 4S (rf4S) in MPS VI cats, the feline 4S cDNA was i...
Mucopolysacchariodosis type VI (MPS VI) is the lysosomal storage disorder caused by the deficient activity of arylsulfatase B (ASB; N-acetylgalactosamine 4-sulfatase) and the subsequent accumulation of the glycosaminoglycan (GAG), dermatan sulfate. In this study, a retroviral vector containing the full-length human ASB cDNA was constructed and used to transduce skin fibroblasts, chondrocytes, a...
BACKGROUND & OBJECTIVES Mucopolysaccharidosis type VI (MPS VI) is a rare, autosomal recessive lysosomal storage disorder caused by deficient enzymatic activity of N-acetyl galactosamine-4-sulphatase resulting from mutations in the arylsulphatase B (ARSB) gene. The ARSB gene is located on chromosome 5q11-q13 and is composed of eight exons. More than hundred ARSB mutations have been reported so f...
Objective(s): Mucopolysaccharidosis VI (MPS VI) or Maroteaux-Lamy syndrome is a rare metabolic disorder, resulting from the deficient activity of the lysosomal enzyme arylsulfatase B (ARSB). The enzymatic defect of ARSB leads to progressive lysosomal storage disorder and accumulation of glycosaminoglycan (GAG) dermatan sulfate (DS), which causes harmful effects on various organs and tissues an...
Mucopolysaccharidosis (MPS) VI is an inheritable lysosomal storage disorder that is often associated with severe orthopedic problems such as hip dysplasia, spinal deformities, and deformities in the skull, knees and hands. We describe the progression and management of three MPS VI cases with focus on their orthopedic problems.
سابقه و هدف: بیماری موکوپلی ساکاریدوزیس نوع شش (MPS VI) یک اختلال ذخیرهای لیزوزومی و اتوزومال مغلوب است که به دلیل کمبود آنزیم آریل سولفاتاز نوع B در بدن و تجمع پیشرونده گلیکوزآمینوگلیکانها در ارگانهای مختلف رخ میدهد. با توجه به شیوع کم این بیماری در ایران و جهان، به گزارش تشخیص یک مورد از این بیماری میپردازیم. گزارش مورد: پسربچهای پنجساله به علت اختلال در رشد و تنگی تنفس به درمانگاه ا...
Background: Mucopolysaccharidosis type-VI (MPS-VI), which is inherited as an autosomal recessive trait, results from the deficiency of N-acetylgalactosamine 4-sulfatase (arylsulfatase B) activity and the lysosomal accumulation of dermatan sulfate. In this study, ARSB mutation analysis was performed on three unrelated patients who were originally from the West Azerbaijan province of Iran. Method...
Ocular changes in some types of the mucopolysaccharidoses (MPS) include corneal clouding, glaucoma, pigmentary retinopathy, optic disc edema, and optic atrophy. Pigmentary retinopathy has been reported in MPS I (Hurler disease), MPS I-S (Scheie syndrome), MPS I-H/S (Hurler/Scheie), MPS II (Hunter disease), MPS III (Sanfilippo syndrome), and MPS IV A (Morquio A syndrome). Clinical signs of retin...
