RAD51C and ovarian cancer: In this study, BC occurs at a mean age of diagnosis of 49.2 and ovarian cancer occurs at a mean age of diagnosis of 59.4 in RAD51C c.571 + 4G > A heterozygotes, and is consistent with a review of 19 studies investigating RAD51C variants in HBOC families, which revealed that RAD51C‐associated BC (n = 56) occurs with a mean age of diagnosis of 48.9 years (range: 27–76) whereas RAD51C‐associated OC (n = 31) occurs with a mean age of diagnosis of 59.1 years (range: 42–81).
