Figure 2. Alteration calling accuracy and concordance with reference platforms. (A) Correlation of short variant MAFs for substitutions and indels called by new vs previously validated assays. MAFs of 102 substitutions and 59 indels were compared in pairs and showed significant correlation (R2 = 0.929). (B) Summary of sensitivity of fusion calling in cell line mixes, separated by detection method (DNA, RNA, or both). (C) High concordance (99%) observed between NGS and Sanger sequencing or PCR validation results. (D) Concordance of alterations between the new assay and other Clinical Laboratory Improvement Amendments (CLIA)–certified reference platforms. The count of positive call and negative call from reference test and our NGS-base assay from the 11 genes/regions are highlighted by different colors: red (alteration was called negative by reference test but positive by our NGS test), steel blue (alteration was called positive in reference test and negative in our NGS test), peach (alteration was called negative in both reference test and negative test), and lime green (alteration was called positive in both reference test and negative test.
