Figure 1: Illustration of AS types and identification of all AS events in TGCT. (a) The seven types of AS events are ES, AP, AT, AD, AA, ME, and RI. (b) UpSet graph showing gene intersections for the seven types of AS events (n = 422 415). Red lines indicate multiple AS events occurring in a single gene. AS: alternative splicing; TGCT: testicular germ cell tumors; ES: exon skip; AP: alternate promoter; AT: alternate terminator; AD: alternate donor site; AA: alternate acceptor site; ME: mutually exclusive exon; RI: retained intron.
