BRCA2 and fallopian tube cancer: More than half were found in BRCA1, followed by BRCA2 and ATM. These data are similar to Pennington, et al. who examined a series of 367 patients with EOC, fallopian tube cancer, or primary peritoneal cancer and found somatic HR mutations in seven genes in 8.7% of patients and germline mutations in 11 HR genes in 24% of patients [7].
