title: Chondroitin 4- and 6-sulfaturia: a new type of inborn error of metabolism?
abstract: A 14-year-old boy was found to excrete excessive amounts of acidic glycosaminoglycans which were predominantly chondroitin 4-sulfate and chondroitin 6-sulfate. Clinical features included dwarfism, mental retardation, coarse facies, deformities of the spine, hip joints and thorax, and granulations in leucocytes. The clinical and biochemical features found in this boy were compared with the known types of mucopolysaccharidosis and it has been concluded that this case is a new type of mucopolysacchariduria.
