Multiple sulfatase deficiency with early severe retinal degeneration.
We report an unusual case of multiple sulfatase deficiency in which neurodegeneration was accompanied by early, severe visual impairment associated with prominent pigmentary retinopathy, suggesting a diagnosis of neuronal ceroid-lipofuscinosis. The levels of arylsulfatases A, B, and C, heparan N-sulfatase, N-acetylgalactosamine-6-sulfate sulfatase, and iduronate-2-sulfate sulfatase were all markedly decreased in cultured skin fibroblasts. Screening tests for mucopolysacchariduria were consistently negative; however, thin-layer chromatographic analysis of isolated urinary glycosaminoglycans showed increased amounts of heparan sulfate.
