摘要： 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, which distinguish fetal DNA from maternal DNA and detect prenatal disorders based on abnormalities in fetal DNA level and methylation status.

摘要： Disclosed herein are methods and kits for selectively amplifying, detecting or quantifying a DNA fragment with a specific end sequence, especially generated following restriction enzyme digestion. This method can be used, for example, to detect a hypomethylated DNA fragment. This methods and kits are especially useful in detecting or quantifying a hypomethylated fetal DNA fragment in a maternal plasma sample containing a corresponding hypermethylated maternal DNA fragment.

摘要： The present invention relates to a new, non-invasive method for detecting chromosomal aneuploidy by analyzing a sample from a pregnant woman. The detection is based on the ratio between the amount of a fetal methylation marker located on a chromosome relevant to the aneuploidy and the amount of a fetal genetic marker located on a reference chromosome, offering improved accuracy.
