Methods are provided for detecting an aneuploidy in a fetus. These methods can be used to detect trisomy 13, 8 or 21, amongst other aneupoloidies. In some embodiments, the methods include selectively purifying fetal DNA from a maternal biological sample using the methylation status of a CpG containing genomic sequence and genotyping the fetus using the purified fetal DNA, thereby detecting aneuploidy in the fetus. |
