Faults in high risk genes cause high grade serous ovarian cancer (HGSOC). This cancer is often lethal in patients. Novel drugs are needed to improve treatment and patient outcomes. We plan to use cells from individuals carrying high risk genes to develop precision models of their disease and then cutting edge methods in genomics and functional screens to identify novel therapeutic targets that can be tested for their potential to treat patients with HGSOC. Ultimately we expect these studies will improve survival rates in patients that get HGSOC because they carry faulty genes.
