  • Title: In utero diagnosis of Gaucher disease.
    Author: Kitagawa T, Owada M, Sakiyama T, Aoki K, Kamoshita S, Amenomori Y, Kobayashi T.
    Journal: Am J Hum Genet; 1978 May; 30(3):322-7. PubMed ID: 98040.
    Abstract:
    Beta-Glucosidase activity measured by synthetic substrate at pH 4.6 was low in the cultured amniotic cells from two pregnant women at risk for juvenile and adult type Gaucher disease. The diagnosis was confirmed by showing a low activity of beta-glucosidase in the skin fibroblasts with a synthetic substrate or in the spleen with a natural substrate, and by ascertaining the presence of Gaucher cells in the fetal tissues. However, considerable activity of beta-glucosidase measured with synthetic substrate was found in the liver of both affected fetuses and in the spleen of one. It is advisable that the determination of beta-glucosidase to confirm prenatal diagnosis of Gaucher disease be done either in the cultured skin fibroblasts or in the spleen, and if in the spleen, with a natural substrate rather than a synthetic one.
