Urinary acid glycosaminoglycan in epidermolysis bullosa dystrophica (recessive type).

A biochemical study was carried out on the urine of an 18-year-old woman with epidermolysis bullosa dystrophica recessive type E.b.d.r.). The urinary acid glycosaminoglycans were separated and subjected to quantitative and qualitative analyses by gel filtration and column chromatography. A hyaluronic acid and the 0.5 M NaCl elution fraction were increased characteristically in the acid glycosaminoglycan.
