A Marker for Prenatal Diagnosis and Monitoring

总结

The present invention relates to new methods for diagnosing a pregnancy-associated disorder by analyzing fetal DNA present in the mother’s blood. More specifically, this invention relies on the discovery that the maspin gene is differentially methylated in fetal DNA and in maternal DNA and provides these new diagnostic methods that distinguish fetal DNA from maternal DNA and detect prenatal disorders based on abnormalities in fetal DNA level and methylation status.

Title: Marker for prenatal diagnosis and monitoring
Usefulness: Marker for prenatal diagnosis and monitoring
Summary: The methods an markers are useful for detecting or monitoring a pregnancy-associated disorder in a woman pregnant with a fetus, where the pregnancy-associated disorder is preeclampsia, preterm labor, hyperemesis gravidarum, ectopic pregnancy, a fetal chromosomal aneuploidy, trisomy 18, trisomy 21, trisomy 13, or intrauterine growth retardation.
Novelty: Detecting or monitoring a pregnancy-associated disorder, e.g. trisomy 18, comprises determining the methylation status of a maspin gene in the blood sample
