Cancers which are more common in people with BRCA2 mutations include: BRCA1- and BRCA2-associated hereditary breast and ovarian cancer syndrome (HBOC) is characterized by an increased risk for female and male breast cancer, ovarian cancer (includes fallopian tube and primary peritoneal cancers), and to a lesser extent other cancers such as prostate cancer, pancreatic cancer, and melanoma primarily in individuals with a BRCA2 pathogenic variant. Women who have inherited a defective BRCA1 or BRCA2 gene are at a greatly elevated risk to develop breast and ovarian cancer. Their risk of developing breast and/or ovarian cancer is so high, and so specific to those cancers, that many mutation carriers choose to have prophylactic surgery.

CHEK2, PALB2, RAD51C), die ebenfalls zu einem erhöhten Risiko für Brustkrebs und zum Teil andere Tumore führen, aber wesentlich seltener betroffen sind. The RAD51 gene provides instructions for making a protein that is essential for repairing damaged DNA. Breaks in DNA can be caused by natural and medical radiation or other environmental exposures, and also occur when chromosomes exchange genetic material in preparation for cell division.
