Vidra et al. assessed 250 Romanian women with breast cancer and 240 with ovarian cancer using Next-Generation Sequencing, finding BRCA mutations in 47 breast cancer patients (63.83% BRCA1, 36.17% BRCA2) and 60 ovarian cancer patients (72% BRCA1, 28% BRCA2). This evidence concerns the gene BRCA1 and breast cancer.
