title: Prenatal diagnosis of mucolipidosis type II on first-trimester amniotic fluid.
abstract: We investigated the possibility of prenatal diagnosis of mucolipidosis type II (ML II) by lysosomal enzyme determination on amniotic fluid obtained at 11 weeks of gestation in three pregnancies at risk. Diagnosis of ML II was made in one case on the basis of increased levels of five lysosomal enzymes tested. The diagnosis was confirmed on cultured chorionic cells, their cultured medium, 17-week amniotic fluid, and fetal plasma obtained for confirmation prior to the termination of pregnancy.
