A 3 1/2-year-old slightly retarded boy with marked deficiency of arylsulfatase A (ASA) activity in leucocytes and fibroblasts and almost no cerebroside sulfatase (CS) activity in fibroblasts was tested with the sulfatide-loading test. On this test his fibroblasts showed impaired degradation. A patho

Metachromatic leukodystrophy is an autosomal recessive inherited lysosomal storage disease. It can be caused by mutations in two different genes, the arylsulfatase A and the prosaposin gene. These genes encode two proteins that are needed for the proper degradation of cerebroside sulfate, a glycolip
In a family with juvenile metachromatic leukodystrophy (sulfatide lipidosis) 2 patients showed residual arylsulfatase A activities of 5--6O/o . The patients' healthy father was characterized biochemicMly by a 39% normal activity of leukoeyte plus plasma arylsulfatase A. The father was further charac
