Interestingly, although MTC tissues were very little subject to the presence of fusion transcripts, confirming the low frequency of chromosomal rearrangement events in this type of neoplasm, the fusion AL391840.3-SH3BGRL2, previously identified in high-grade serous ovarian cancer [53], was retrieved in two MTC patients in our cohort (Table 3). This evidence concerns the gene SH3BGRL2 and ovarian serous adenocarcinoma.
