In terms of ovarian cancer, a number of fusion genes has also been identified [26]; however, the elucidation of their functions and mechanisms is limited only in several fusion genes, including SLC25A40-ABCB1, MAN2A1-FER, BCAM-AKT2, FHL2-GLI2, YWHAE-FAM22A, JAZF1-SUZ12, and FGFR3-TACC3 [27,28,29], and the clinical application of these findings is not available. The gene discussed is GLI2; the disease is ovarian cancer.
