    Abstract: Die Erfindung betrifft Verfahren und Mittel zur Diagnostik von Tumoren, insbesondere zur Frühdiagnostik(Vorsorge)und zur Unterscheidung von benignen und malignen Tumoren mittels PCR, insbesondere in Körperflüssigkeiten. Das erfindungsgemäße Verfahren zeichnet sich durch eine Kombination einer Präamplifikation mittels PCR aus,in der methylierte DNA-Sequenzen stärker amplifiziert werden als nicht-methylierte DNA-Sequenzenund eine anschließende Quantifizierung mittels einer speziellen digitalen PCR, in der deutlich mehr DNA eingesetzt wird, als nach dem Stand der Technik üblich. Wie anhand von Vergleichsdaten gezeigt wird, ermöglicht die Erfindung vorteilhaft eine deutlich zuverlässige Aussage, ob eine maligne Tumorerkrankung vorliegt oder nicht. Die Erfindung eignet sich zum Screening (Vorsorge), zur Verlaufskontrolle einer Tumorerkrankung, insbesondere zum Ausschluss einerminimalen Resterkrankung (MRD) und zur Differentialdiagnose von malignen Karzinomen von benignen Tumoren.

    Abstract: The present invention relates to methods for detecting a chromosomal aneuploidy in a foetus carried by a pregnant female. Such methods are based on one or more of particular configurations and/or detections and/or analyses of two or more regions of DNA, including those that show differential methylation between DNA that originates from cells of a foetus (and/or the placenta of a foetus) and DNA of maternal origin. Such methods utilise a sample taken from said pregnant female, which sample comprises DNA that originates from cells of a foetus and/or the placenta of a foetus in admixture with differently methylated DNA of maternal origin. Such methods have diagnostic, prognostic and/or predictive utility; in particular for the detection/diagnosis of chromosomal aneuploidy, such as a trisomy, in a foetus, and/or for detecting an increased risk of a pregnant female suffering from or developing a pregnancy-associated medical condition. The present invention also relates to compositions, kits, computer program products and other aspects that may be used in, useful for or related to the practice of such methods.

    Abstract: The contributions of different tissues to a DNA mixture are determined using methylation levels at particular genomic sites. Tissue-specific methylation levels of M tissue types can be used to deconvolve mixture methylation levels measured in the DNA mixture, to determine fraction contributions of each of the M tissue types. Various types of genomic sites can be chosen to have particular properties across tissue types and across individuals, so as to provide increased accuracy in determining contributions of the various tissue types. The fractional contributions can be used to detect abnormal contributions of a particular tissue, indicating a disease state for the tissue. A differential in fractional contributions for different sizes of DNA fragments can also be used to identify a diseased state of a particular tissue. A sequence imbalance for a particular chromosomal region can be detected in a particular tissue, e.g., identifying a location of a tumor.

    Abstract translation: 使用特定基因组位点的甲基化水平测定不同组织对DNA混合物的贡献。 M组织类型的组织特异性甲基化水平可用于对在DNA混合物中测量的混合甲基化水平进行去卷积,以确定每种M组织类型的分数贡献。 可以选择各种类型的基因组位点以在组织类型和个体之间具有特定的性质,以便提供确定各种组织类型的贡献的更高精度。 分数贡献可用于检测特定组织的异常贡献,指示组织的疾病状态。 不同大小的DNA片段的分数贡献差异也可用于鉴定特定组织的病态。 可以在特定组织中检测特定染色体区域的序列不平衡,例如识别肿瘤的位置。
