Our finding of a BC onset age of 43 in a RAD51D GPV carrier is consistent with the study of Yang et al., as they found that the BC onset age in RAD51D GPV carriers (n = 30) was below the age of 50 years in over 60% of cases, with over 33% being between the ages of 40 and 49 [5]. This evidence concerns the gene RAD51D and breast cancer.
