The Morquio syndrome is a spondyloepiphyseal dysplasia characterized by excretion in urine of excessive amounts of keratan sulfate and chondroitin sulfate. To investigate the enzymic basis of this disease, assays for sulfatase were performed using chick embryo chondroitin sulfate and rat chondrosarcoma chondroitin 4-sulfate as substrates. The data obtained, using skin fibroblasts as an enzyme source, indicate that Morquio's syndrome is a deficiency of chondroitin sulfate N-acetylhexosamine sulfate sulfatase.
