Identifying the need for a multidisciplinary approach for early recognition of mucopolysaccharidosis VI (MPS VI).
Mucopolysaccharidosis VI (MPS VI, Maroteaux-Lamy syndrome) is caused by deficient activity of the enzyme, N-acetylgalactosamine-4-sulfatase, resulting in impaired degradation of the glycosaminoglycan dermatan sulfate. Patients experience a range of manifestations including joint contractures, short stature, dysostosis multiplex, coarse facial features, decreased pulmonary function, cardiac abno...
متن کاملNatural history and galsulfase treatment in mucopolysaccharidosis VI (MPS VI, Maroteaux-Lamy syndrome)--10-year follow-up of patients who previously participated in an MPS VI Survey Study.
Mucopolysaccharidosis VI (MPS VI) is a clinically heterogeneous and progressive disorder with multiorgan manifestations caused by deficient N-acetylgalactosamine-4-sulfatase activity. A cross-sectional Survey Study in individuals (n = 121) affected with MPS VI was conducted between 2001 and 2002 to establish demographics, urinary glycosaminoglycan (GAG) levels, and clinical progression of disea...
متن کاملSpinal cord compression in young children with type VI mucopolysaccharidosis.
Spinal cord compression (SCC) is a known complication of mucopolysaccharidosis type VI (MPS VI) secondary to atlantoaxial subluxation, craniovertebral stenosis, posterior longitudinal ligament hypertrophy, or dural thickening. SCC is expected to occur in the natural history of the disease, regardless of enzyme replacement therapy (ERT), as intravenous enzyme does not cross the blood-brain barri...
متن کاملDiagnostic difficulties in patients with attenuated form of MPS VI
Background Mucopolysaccharidosis VI (MPS VI, Maroteaux-Lamy syndrome) is an autosomal recessive lysosomal storage disorder determined by mutations in the arylsulfatase B gene located in chromosome 5. Pathogenic mutations of this gene result in reduced or absent activity of enzyme arylsulfatase B (N-acetylgalactosamine 4-sulfatase, ARSB). Incomplete degradation and cellular accumulation of glyco...
متن کاملMucopolysaccharidosis VI
Mucopolysaccharidosis VI (MPS VI) is a lysosomal storage disease with progressive multisystem involvement, associated with a deficiency of arylsulfatase B leading to the accumulation of dermatan sulfate. Birth prevalence is between 1 in 43,261 and 1 in 1,505,160 live births. The disorder shows a wide spectrum of symptoms from slowly to rapidly progressing forms. The characteristic skeletal dysp...
