DST and neoplasm: As shown in Figure 5, we confirmed an aberrant increase of cassette exon skipping in tumor specimens for PACSIN2 exon 8, DIAPH1 exon 2, FGFR1OP2 exon 4, MARK3 exon 16, DST exon 93, LMO7 exon 10, and RBM5 exon 7, whereas ADD3 exon 13, MAP3K7 exon 12, and MARK2 exon 15 were preferentially included in tumor specimens.
