Sulfatide excreting heterozygous carrier of juvenile metachromatic leukodystrophy or asymptomatic patient of adult metachromatic leukodystrophy.
1975
In a family with juvenile metachromatic leukodystrophy (sulfatide lipidosis) 2 patients showed residual arysulfatase A activities of 5--6%. The patients' healthy father was characterized biochemically by a 39% normal activity of leukocyte plus plasma arylsulfatase A. The father was further characterized by a high sulfatide excretion (0.2--0.5 mg/I urine) and, paradoxically, by a normal sulfatide degrading enzyme activity in vitro. This special carrier is suspected to be heterozygous for a) arylsulfatase A deficiency and b) arylsulfatase A (sulfatidase) lability. This presumed additional genetic defect could be the cause of the sulfatide excretion which, in turn, would be a sign of the precl…
Clinical and histological diagnosis of a case of familial adult metachromatic leucodystrophy
1974
Die detaillierte nosographische Analyse eines 25jahrigen Patienten mit adulter metachromatischer Leukodystrophie wird mitgeteilt. Der Patient zeigt langsam progrediente psychische, charakterliche, intellektuelle, zentralund periphernervose Veranderungen. — Die biochemische Diagnostik ergab einen weitgehenden Arylsulfatase A-Mangel in Urin und Leukocyten sowie eine erhohte Sulfatidausscheidung im Urin (2–7 mg je Liter). — Durch histochemische Untersuchungen einer Nervus suralis-Biopsie wurde metachromatisches Speichermaterial nachgewiesen.
