Previously, Hoogstraat et al. [30] found rearrangement of DPP9 in a high-grade serous ovarian carcinoma by means of whole-genome mate-pair sequencing, a DPP9-PAX2 in-frame rearrangement with the breakpoint after exon 11 in DPP9, i.e., close to the breakpoint identified in the present DPP9-PPP6R3 fusion. Here, DPP9 is linked to ovarian serous carcinoma.
