Using newer Ribonucleic Acid (RNA) sequencing technologies, the 15 cases of IMT were found to harbor various fusion partners of ALK, including CLTC, TPM3, EML4, SEC31A, TRAF3, LRRFIP1, FN1, NUMA1, RRBP1, TNS1, and DCTN1. Both cases of PSC harbored EML4-ALK. This evidence concerns the gene TRAF3 and inflammatory myofibroblastic tumor.
