It has been found that approximately 80% of ovarian cancers have DPH1 gene deletions and that ELP3 is up-regulated in breast cancer cells, which in turn leads to increased levels of the oncoprotein DEK (Chen and Behringer 2004, 2005; Kong et al. 2011; Delaunay et al. 2016). The gene discussed is DPH1; the disease is breast cancer.
