Publication number: 20240170094Abstract: Disclosed herein are methods, systems, and apparatus for estimating a fetal DNA percentage in a biological sample. In some embodiments, methods may include receiving one or more sequence tags for each of a plurality of DNA fragments in the biological sample. In addition, methods may include determining genomic positions for the sequence tags. Also, methods may include for each of one or more genomic regions, determining, with a computer system, a respective amount of DNA fragments within the genomic region from sequence tags having genomic positions within the genomic region; normalizing the respective amount to obtain a respective density; and comparing the respective density to a reference density to identify whether the respective density is statistically different from the reference density. Further, methods may include estimating the fetal DNA percentage from the one or more genomic regions identified to have respective densities statistically different than the reference densities.Type: ApplicationFiled: January 29, 2024Publication date: May 23, 2024Inventors: Yuk-Ming Dennis Lo, Kwan Chee Chan, Peiyong Jiang, Cheuk Yin Jandy Yu, Rossa Wai Kwun Chiu

Patent number: 11984195Abstract: 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.Type: GrantFiled: October 15, 2018Date of Patent: May 14, 2024Assignee: The Chinese University of Hong KongInventors: Rossa Wai Kwun Chiu, Kwan Chee Chan, Yuk-Ming Dennis Lo, Peiyong Jiang, Kun Sun
