title: Antenatal diagnosis of Hurler's syndrome.
abstract: Hurler's syndrome was diagnosed antenatally in the two consecutive pregnancies of a mother with one affected child. In both instances, diagnosis was based upon a demonstration of the presence of unusual glycosaminoglycan components in the amniotic fluid, of abnormal metabolic activity in cultured amniotic fluid cells, and a deficiency of the lysosomal enzyme alpha-L-iduronidase in these cell homogenates. Bothe pregnancies were terminated before the 24th week and the diagnosis was confirmed by biochemical studies of the fetal livers.
