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, Maroteaux-Lamy syndrome is a lysosomal storage disorder with progressive, multisystem involvement caused by deficiency of the lysosomal enzyme N-acetylgalactosamine-4-sulfatase leading to accumulation of the glycosaminoglycan, keratan sulfate. Enzyme replacement therapy (ERT) has been shown to clinically benefit affected individuals. A combined treatment regime of...

Cases of metaphysial dysplasia have been recorded by Pyle (1931), Bakwin and Krida (1937) and Hermel, Gershon-Cohen and Jones (1953). Jansen (1934) described a form of metaphysial dysplasia which he termed metaphysial dysostosis. Similar cases were reported by Cameron, Young and Sissons (1954), Lenk (1956), Maroteaux and Lamy (1960), Evans and Caffey (1958), and Gram, Fleming, Frame and Fine (1...
