Germline Mutation in 1338 BRCA-Negative Chinese Hereditary Breast and/or Ovarian Cancer Patients

Prevalence and spectrum of BRCA germline variants in mainland Chinese familial breast and ovarian cancer patients

Germline mutations in BRCA1 and BRCA2 are the most penetrating genetic predispositions for breast and ovarian cancer, and their presence is largely ethnic-specific. Comprehensive information about the prevalence and spectrum of BRCA mutations has been collected in European and North American populations. However, similar information is lacking in other populations, including the mainland Chines...

Breast cancer following ovarian cancer in BRCA mutation carriers.

IMPORTANCE BRCA mutation carriers are at increased risk of developing breast cancer. However, the incidence of breast cancer after a diagnosis of epithelial ovarian cancer (EOC), one of the tubal/peritoneal cancers collectively referred to as pelvic serous carcinomas, is not well known. Optimal breast cancer surveillance and detection for these patients have also not been well characterized. ...

Prioritizing Variants in Complete Hereditary Breast and Ovarian Cancer Genes in Patients Lacking Known BRCA Mutations.

BRCA1 and BRCA2 testing for hereditary breast and ovarian cancer (HBOC) does not identify all pathogenic variants. Sequencing of 20 complete genes in HBOC patients with uninformative test results (N = 287), including noncoding and flanking sequences of ATM, BARD1, BRCA1, BRCA2, CDH1, CHEK2, EPCAM, MLH1, MRE11A, MSH2, MSH6, MUTYH, NBN, PALB2, PMS2, PTEN, RAD51B, STK11, TP53, and XRCC2, identifie...

Risk of ovarian cancer in BRCA1 and BRCA2 mutation-negative hereditary breast cancer families.

Women from site-specific hereditary breast cancer families who carry a BRCA1 or BRCA2 mutation are at increased risk for ovarian cancer. It is less clear, however, whether individuals from hereditary breast cancer families who do not carry such a mutation are also at increased ovarian cancer risk. To determine whether women from BRCA mutation-negative hereditary breast cancer families are at in...
