These analyses revealed several novel rearrangements that were predicted to result in in-frame protein fusions in ovarian endometrioid carcinomas, including ATAD1–PTEN, the neurofibromin genes NF1 and NF2, as well as cyclin-dependent and polo-like kinase (PLK) genes CDK7 and PLK5 (Fig. 3C). This evidence concerns the gene PLK5 and ovarian endometrioid carcinoma.
