Comparison of exon-level copy number variants in CytoScan XON assay and next-generation sequencing in clinical samples.

Background And Aims: Next-generation sequencing (NGS)-based copy number variants (CNVs) have high false-positive rates. The fewer the exons involved, the higher the false-positive rate. A CytoScan XON assay was developed to assess exon-level CNVs.
