Some of the genes in our selection have not been associated with increased risk of ovarian cancer (e.g.CHEK1, CHEK2, MRE11, ABRAXAS11), but we included them in our analysis as somatic variants in some of these genes may be associated with an increased sensitivity to PARPi [26,52], with further research being performed in this area. Here, CHEK2 is linked to ovarian cancer.
