Abstract
Galactosylceramide beta-galactosidase activity was assayed in cultured amniotic fluid cells from two pregnancies at risk for Krabbe's leucodystrophy. The elective termination of one pregnancy was carried out after demonstration of a severe deficiency of galactosylceramide beta-galactosidase activity. The diagnosis of Krabbe's leucodystrophy in the affected fetus was confirmed enzymatically by a deficiency of galactosylceramide beta-galactosidase inbrain, liver, kidney, and cultured skin fibroblasts, and histologically by the ultrastructural demonstration of the typical intracellular inclusions in cells of the spinal cord.
