摘要： The present invention is directed to methods of detecting nucleic acids in a biological sample. The method is based on a novel combination of a base extension reaction, which provides excellent analytical specificity, and a mass spectrometric analysis, which provides excellent specificity. The method can be used, for example, for diagnostic, prognostic and treatment purposes. The method allows accurate detection of nucleic acids that are present in very small amounts in a biological sample. For example, the method of the present invention is preferably used to detect fetal nucleic acid in a maternal blood sample; circulating tumor-specific nucleic acids in a blood, urine or stool sample; and donor-specific nucleic acids in transplant recipients. In another embodiment, one can detect viral, bacterial, fungal, or other foreign nucleic acids in a biological sample.

摘要： This application provides the use of novel fetal markers for prenatal diagnosis and monitoring of certain pregnancy-related conditions. More specifically, the invention resides in the discovery that certain CpG islands located on fetal chromosome 21 demonstrate a methylation profile that is distinct from that of the corresponding CpG islands located on maternal chromosome 21. This application also provides kits for diagnosing or monitoring of the relevant conditions.

摘要： The non-invasive detection of fetal chromosomal aneuploidies is demonstrated. Alleles of fetal RNA-SNPs present in a biological sample (e.g. maternal blood) containing fetal RNA are detected and quantified in order to determine the ratio of the alleles. This ratio is compared to a standard control consisting of euploid fetuses. Deviation of allele ratio indicates the presence of chromosomal aneuploidy.

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： The present invention provides an efficient way for high throughput haplotype analysis. Several polymorphic nucleic add markers, such as SNPs, can be simultaneously and reliably determined through multiplex PCR of single nucleic acid molecules in several parallel single molecule dilutions and the consequent statistical analysis of the results from these parallel single molecule multiplex PCR reactions results in reliable determination of haplotypes present in the subject. The nucleic acid markers can be of any distance to each other on the chromosome. In addition, an approach wherein overlapping DNA markers are analyzed can be used to link smaller haplotypes into larger haplotypes. Consequently, the invention provides a powerful new tool for diagnostic haplotyping and identifying novel haplotypes.

摘要： Chromosomal abnormalities are responsible for a significant number of birth defects, including mental retardation. The present invention is related to methods for non-invasive and rapid, prenatal diagnosis of chromosomal abnormalities based on analysis of a maternal blood sample. The invention exploits the differences in DNA between the mother and fetus, for instance differences in their methylation states, as a means to enrich for fetal DNA in maternal plasma sample. The methods described herein can be used to detect chromosomal DNA deletions and duplications. In a preferred embodiment, the methods are used to diagnose chromosomal aneuploidy and related disorders, such as Down's and Turner's Syndrome.
