Analytical Validity: Help
Deletion/duplication analysis is performed with ThermoFisher’s CytoScan XON array, which provides exon-level resolution for detection of copy number variants. Analysis is limited to the targeted regions. When a copy number change is detected that extends into flanking genes, the genomic coordinates of the full variant will be reported. Copy number … View more
