  • Marker for early detection of human hydatidiform moles and choriocarcinomas
    Patent number: 5141849
    Abstract: The present invention relates to a DNA segment comprising linked pregnancy-specific beta.sub.1 -glycoprotein (PS.beta.G) genes encoding PSGGA protein and PSGGB protein. The invention further relates to a probe (DNA, RNA or peptide probe) specific for PSGGB mRNA or protein expressed in human hydatidiform molar trophoblastic tissue and to a bioassay for the detection of gestational trophoblastic diseases. The PSGGB-specific probes of the present invention hybridized most strongly with RNA from molar trophoblastic tissue, suggesting that the PSGGB-like species may be the gene preferentially expressed in gestational trophoblastic diseases.
