    摘要： This application describes the discovery that, in a pregnant woman, certain genes (such as RASSF1A, APC, CASP8, RARB, SCGB3A1, DAB2IP, PTPN6, THY1, TMEFF2, and PYCARD) originated from a fetus are highly methylated, whereas the same genes of maternal origin are unmethylated. This discovery allows the easy detection of one or more of these methylated fetal genes in a biological sample from a pregnant woman, serving as a universal indicator of the presence of fetal DNA in the sample. These fetal methylation markers are particularly useful as positive controls for a non-invasive analytical process during which the quality and quantity of fetal DNA are monitored. These newly identified fetal markers can also be measured directly for diagnosis of certain pregnancy-related conditions.

    摘要： The present invention provides a method for analyzing nucleic acids for their lengths and relative abundance in a sample, based on digital amplification of individual template molecules. This invention has many applications, including those in noninvasive prenatal diagnosis, transplantation monitoring, and the detection and monitoring of cancers and virus-associated diseases.
