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...
Maroteaux-Lamy disease, also known as mucopolysaccharidosis (MPS) VI, is an MPS disorder caused by mutations in the ARSB gene encoding for the lysosomal enzyme arysulfatase B (ARSB). Deficient ARSB activity leads to lysosomal accumulation of dermatan sulfate in a wide range of tissues and organs. There are various animal models of MPS VI that have been well characterized from a biochemical and ...
Mucopolysaccharidosis VI (MPS VI), or Maroteaux-Lamy syndrome, is an autosomal recessive lysosomal storage disorder caused by deficient activity of the enzyme arylsulfatase B (ASB). Progressive accumulation of glycosaminoglycans (GAGs) in organs and tissues leads to the development of multisystem clinical manifestations. The presentation of MPS VI is genotypically and phenotypically diverse, wi...
Mucopolysaccharidosis type VI (MPS VI, Maroteaux-Lamy syndrome, McKusick #253200) is a lysosomal storage disorder that is caused by a deficiency in the lysosomal exohydrolase N-acetylgalactosamine-4-sulphatase (4-sulphatase, EC 3.1.6.1). We report a patient with no obvious clinical signs of MPS VI that has 5% of normal 4-sulphatase catalytic capacity. This patient represents an index case for t...
Bone marrow transplantation (BMT) is a therapeutic option for patients with genetic storage diseases. Between 1979 and 2002, eight patients, four females and four males (1 to 13 years old) were submitted to this procedure in our center. Six patients had mucopolysaccharidosis (MPS I in 3; MPS III in one and MPS VI in 2), one had adrenoleukodystrophy (ALD) and one had Gaucher disease. Five patien...
We analyzed placental tissue in one fetus with MPS II (iduronate sulphatase deficiency) and another with MPS VI (arylsulfatase B deficiency). Both were diagnosed prenatally, but families decided to continue pregnancies and placentas were collected at birth. We were able to demonstrate early storage of GAGs in both diseases by GAG measurement and microscopy analysis. Our results suggest that som...
Mucopolysaccharidosis type VI (MPS VI) is an autosomal recessive multisystem lysosomal storage disorder, which is characterized by the deficiency of the enzyme arylsulfatase B encoded by the ARSB gene. Treatment of this disease with enzyme-replacement therapy (ERT) improves the clinical status of and generates hope for MPS VI patients. However, only few reports on patients with MPS VI treated b...
The Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI; MPS VI) is a lysosomal storage disease caused by deficiency of the enzyme arylsulphatase B (ASB). A human ASB cDNA has been subcloned into the retroviral vector pXT1 containing the bacterial neomycin-resistance gene and an internal thymidine kinase promoter for transcription of the inserted gene. Replication defective retrovirus was ge...
Mucopolysaccharidosis type VI (MPS VI), also called Maroteaux-Lamy syndrome, is an autosomal recessive lysosomal storage disorder caused by deficiency of a specific enzyme required for glycosaminoglycan catabolism. Deficiency in the N-acetylgalactosamine-4-sulfatase (4S) enzyme, also called arylsulfatase B (ARSB), may have profound skeletal consequences. In MPS VI, partially degraded glycosamin...
Mucopolysaccharidosis type VI (MPS VI) is a progressive, multisystem autosomal recessive lysosomal disorder resulting from deficient N-acetylgalactosamine-4-sulphatase (ASB) and the consequent accumulation of glycosaminoglycan (GAG). Preclinical and clinical studies had demonstrated clinical benefits of early initiation of systemic therapies in patients with MPS. In this case report, two siblin...
