Cell lines are mixed to create multiple levels of aneuploidy. The calculated copy number at the affected aneuploid region displayed correlation with the aneuploid percentage using automatic identification via the Ion Reporter on the Ion S5 system (1a), and using manual identification via the BlueFuse Multi on the Miseq system (1b). As the number of aneuploid cells in the mixtures increases, the copy number of the regions with segmental deletion or whole-chromosome duplication decreases or increases on both the NGS systems.
