What is Mucopolysaccharidosis VI?

  • Mucopolysaccharidosis VI: A lysosomal storage disorder that is caused by a deficiency of the ability to metabolise glycosaminoglycans.
  • Mucopolysaccharidosis VI: An inborn error of metabolism characterized by arylsulfatase B (EC deficiency preventing degradation of mucopolysaccharides with their accumulation in soft tissues causing obstructions and compression of the blood vessels, trachea, and peripheral nerves, and disruption of normal bone development, associated with the phenotype similar to that in MPS I but generally normal intelligence and mental retardation reported in a few isolated cases. Three basic types are recognized: Maroteaux-Lamy syndrome type B Synonym: mucopolysaccharidosis (MPS) VI B A mild type marked by usually normal childhood until about 6 years of age when short stature, Legg-Perthes-like changes of the hips, aortic stenosis, spinal deformities, corneal clouding, survival into adulthood. The intermediate type has the phenotype similar to that in mucolipidosis III with coarse Hurler-like facies, stiff joints with decreased mobility, and short stature. The severe type (sometimes designated Maroteaux-Lamy syndrome type A Synonym: mucopolysaccharidosis (MPS) VI A A severe typs usually associated with onset of symptoms in early childhood, a rapidly progressive course, and death in adolescence. Short stature, coarse facies, hyperextended head, corneal clouding, defective hearing, heart abnormalities, and musculoskeletal anomalies are the main characteristics.
