title: Mosaicism for sulfoiduronate sulfatase deficiency in carriers of Hunter's syndrome.
abstract: Using an assay for sulfoiduronate sulfatase based on the degradation of 35S mucopolysaccharides in a cell-free system, two clonal populations have been demonstrated in fibroblasts of heterozygotes for Hunter's syndrome. The locus responsible for sulfoiduronate sulfatase deficiency in this X-linked mucopolysaccharidosis is therefore subjected to dosage compensation in females.
