    摘要: The present invention provides, inter alia, a method for generating a genome-wide epigenomic map, comprising a correlation between methylation variable CpG positions (MVP) and genomic DNA sample types. MVP are those CpG positions that show a variable quantitative level of methylation between sample types. Particular genomic regions of interest (ROI) provide preferred marker sequences that comprise multiple, and preferably proximate MVP, and that have novel utility for distinguishing sample types. The epigenic maps have broad utility, for example, in identifying sample types, or for distinguishing between and among sample types. In a preferred embodiment the epigenomic map is based on methylation variable regions (MVP) within the major histocompatibility complex (MHC), and has utility, for example, in identifying the cell or tissue source of a genomic DNA sample, or for distinguishing one or more particular cell or tissue types among other cell or tissue types. Analysis of epigenetic characteristics of one, or of a set of nucleic acid sequences, in the context of an inventive epigenomic map, allows for the determination of an origin of the nucleic acids.

    摘要: Aspects of the present invention relate to the determination of the DNA methylation level at one or more CpG position within cells of a defined type in a tissue sample. This methylation level is deduced from the total DNA methylation level of all cells of the sample and from the content of said cells of interest. In aspects of the invention, the cell content is determined by means of histopatholoy, staining methods, antibodies, expression analysis or DNA methylation analysis.
