RNA was extracted from formalin-fixed paraffin-embedded (FFPE) tissue using Amsbio’s ExpressArt FFPE Clear RNA Ready kit (Amsbio LLC, Cambridge, MA). One case was tested on the TruSight RNA Fusion Panel (Illumina, San Diego, CA), using 100 ng total RNA for RNA-sequencing libraries preparation.9 (link) Fragment length was assessed with an RNA 6000 chip on an Agilent Bioanalyzer (Agilent Technologies, Santa Clara, CA). The sample was subjected to targeted RNA sequencing on an Illumina MiSeq at eight samples per flow cell (~3 million reads per sample). All reads were independently aligned with STAR (version 2.3) and BowTie2 against the human reference genome (hg19) for Manta-Fusion and TopHat-Fusion analysis, respectively. The second case was tested by Anchored Multiplex RNA sequencing assay using the Archer FusionPlex Solid tumor Kit (Archer, Boulder, CO).10 (link) Anchored Multiplex polymerase chain reaction amplicons were sequenced on Illumina MiSeq, and the data were analyzed using the Archer software.
