The PCR products were purified with ExoSAP-IT (Affymetrix, USA) and subjected to Sanger Sequencing (Macrogen, USA). The amplicons containing the predicted genomic mutations were sequenced using BigDye Terminator Cycle Sequencing Kit v3.1 on the ABI Prism 3730×l DNA Analyzer (Applied Biosystems, USA). All Sanger validation figures are in
To assess the sensitivity of judging absence of a mutation in one phase that is present in the other phase, we studied 15 variants in the panel that are absent in one of the samples in WES, with median WES depth 117 [10-402]. Using CancerScan6 (link), we found that no read reported the variant in the sample where it was deemed absent by WES (
