A rare lysosomal storage disease characterized by a wide spectrum of manifestations, notably skeletal dysplasia including short stature, dysostosis multiplex and degenerative joint disease, with progressive multisystem involvement, associated with a deficiency of arylsulfatase B (ASB) leading to the accumulation of dermatan sulfate and chondroitin-4-sulfate.
