title: Diagnosis of the mucopolysaccharidoses using cultured skin fibroblasts and amniotic fluid cells.
abstract: Assay of alpha-L-iduronidase, heparin sulphamidase, N-acetyl-alpha-D-glucosaminidase, arylsulphatase B, alpha-L-fucosidase, beta-glucuronidase, beta-galactosidase and alpha-D-mannosidase in cultured cells is described. Activities in deficient fibroblast strains are compared to control fibroblast strains. The first case of Sanfilippo B in the United Kingdom is reported. A comparison of enzyme activities in cultured fibroblasts and amniotic fluid cells is made.
