An RUO WTS assay missed 30.0% (6/20) of clinically relevant fusions detected with RNA CGP (FoundationOne RNA or FoundationOne Heme) in clinical samples. Table denotes whether fusions were detected or not detected/(†) detected below reporting confidence thresholds in one or more replicates. Two sample replicates per assay were tested unless indicated. Asterisks (*) indicate samples with only a single replicate due to limited residual sample for testing. CGP, comprehensive genomic profiling; RUO, research use only; WTS, whole transcriptome sequencing.
