摘要
Various applications can use fragmentation patterns related of cell-free DNA, e.g., plasma DNA and serum DNA. For example, the end positions of DNA fragments can be used for various applications. The fragmentation patterns of short and long DNA molecules can be associated with different preferred DNA end positions, referred to as size-tagged preferred ends. In another example, the fragmentation patterns relating to tissue-specific open chromatin regions were analyzed. A classification of a proportional contribution of a particular tissue type can be determined in a mixture of cell-free DNA from different tissue types. Additionally, a property of a particular tissue type can be determined, e.g., whether a sequence imbalance exists in a particular region for a tissue type or whether a pathology exists for the tissue type.
