RAD51C and ovarian cancer: BRCA1 and BRCA2 encode proteins involved in recombinational repair of damaged DNA [11] and it has been found that mutations in other genes involved in the repair of DNA damage by homologous recombination, including e.g., RAD51C, RAD51D, BRIP1, PALB2, and CHEK2 may be associated with ovarian cancer risk [15,16,17,18,19,20,21].
