Results of partial aneuploidy screening performed with the VeriSeq NIPT Solution v1 assay and the WisecondorX software, using cffDNA from the maternal bloodstream. Z-score variations (vertical axis) for the different cytogenetic positions (horizontal axis) are shown. Note that the distances between the cytogenetic bands are presented in megabases (Mb). A Results showing a gain of approximately 25 Mb in the long arm of chromosome 3 (light blue bar) with a mean Z-score value of 13.5. B Results showing a loss of approximately 30 Mb in the short arm of chromosome 5 (orange bar) with a mean Z-score value of − 13.95
