At least eight genes were found to be significantly associated with breast cancer risk: BRCA1 (MIM#113705), BRCA2 (MIM#600185), ATM (MIM#607585), BARD1 (MIM #601593), CHEK2 (MIM#604373), PALB2 (MIM#610355), RAD51C (MIM#602774), and RAD51D (MIM#602954) [4,5,6]. Here, RAD51C is linked to breast cancer.
