The MPS results of maternal peripheral blood DNA, fetal DNA, placental DNA. A-B. The maternal information of chromosome 18 and X, based on the sequencing result of maternal peripheral blood DNA, suggests a euploid status of the maternal background. C-D. The sequencing results of fetal DNA, where the copy ratio (1.5) of chromosome 18 in C indicated the trisomy 18 status in the fetus, the copy ratio (1.0) of chromosome X in D indicated the euploid status of chromosome X in the fetus. E-F. The sequencing results of the placental DNA, where the copy ratio (1.0-1.5) of chromosome 18 in E indicated a low level of mosacism of trisomy 18, the copy ratio (0.5-1.0) in F indicated a low level of mosaicism of monosomy X.
