Patent number: 8927216Abstract: This application describes the discovery that, in a pregnant woman, certain genes (such as RASSF1A, APC, CASP8, RARB, SCGB3A1, DAB2IP, PTPN6, THY1, TMEFF2, and PYCARD) originated from a fetus are highly methylated, whereas the same genes of maternal origin are unmethylated. This discovery allows the easy detection of one or more of these methylated fetal genes in a biological sample from a pregnant woman, serving as a universal indicator of the presence of fetal DNA in the sample. These fetal methylation markers are particularly useful as positive controls for a non-invasive analytical process during which the quality and quantity of fetal DNA are monitored. These newly identified fetal markers can also be measured directly for diagnosis of certain pregnancy-related conditions.Type: GrantFiled: September 14, 2012Date of Patent: January 6, 2015Assignee: The Chinese University of Hong KongInventors: Yuk-Ming Dennis Lo, Rossa Wai Kwun Chiu, Stephen Siu Chung Chim, Chunming Ding, Kwan Chee Chan, Hing Nam Ivy Wong, Ka Chun Ryan Yuen
