SPECIFIC AMPLIFICATION OF FETAL DNA SEQUENCES FROM A MIXED, FETAL-MATERNAL SOURCE

摘要

The present invention provides a method of selectively amplifying fetal DNA sequences from a mixed, fetal-maternal source. This method utilizes differential methylation to allow for the selective amplification of trophoblast/fetal specific sequences from DNA mixtures that contain a high proportion of non-trophoblast/fetal DNA. The invention also provides methods of using the amplified fetal DNA sequences for aneuploidy detection.
