Dual-color FISH was performed on tumor touchprint preparations from at least two different tumor samples to validate fusion transcripts with MALAT1 as the 5’ fusion partner in combination with the AHNAK, RPPH1, MUC16, RMRP, SYNE2, COL3A1, COL1A2, EIFA2, MACF1, C3, CANX and XIST as the 3’ fusion partners. This evidence concerns the gene XIST and neoplasm.
