In a previous study, we showed that two tumors carrying the TPR/NTRK1 rearrangement contained structurally different oncogenes named TRK-T1 and TRK-T2.     ///    "In this paper, we report (1) the cDNA structure of TRK-T2, (2) evidence that TRK-T2 is generated by different rearrangements in two thyroid tumors, and (3) a detailed analysis of the three different TPR/NTRK1 rearrangements.
