BRCA1 and BRCA2 as ovarian cancer susceptibility genes [PDF]

open access: yesCarcinogenesis, 2005
Individuals carrying germline mutations in one allele of the BRCA1 or BRCA2 genes are at significantly increased risk of developing cancer. Although the increased risk of breast cancer is often highlighted, cancer at several other sites is also considerably more common in these individuals.

Common breast cancer susceptibility alleles are associated with tumour subtypes in BRCA1 and BRCA2 mutation carriers: results from the Consortium of Investigators of Modifiers of BRCA1/2

open access: yes, 2011
The associations of the 12 SNPs with risk for BRCA1 and BRCA2 carriers differ by ER-positive or ER-negative breast cancer status. The apparent differences in SNP associations between BRCA1 and BRCA2 carriers, and non-carriers, may be explicable by ...

Effects of germline and somatic events in candidate BRCA-like genes on breast-tumor signatures.

open access: yesPLoS ONE, 2020
Mutations in BRCA1 and BRCA2 cause deficiencies in homologous recombination repair (HR), resulting in repair of DNA double-strand breaks by the alternative non-homologous end-joining pathway, which is more error prone.

The Landscape of BRCA Mutations among Egyptian Women with Breast Cancer

open access: yesOncology and Therapy, 2023
Background Deleterious germline mutations in BRCA1 and BRCA2 genes are associated with a high risk of breast and ovarian cancer. In many developing countries, including Egypt, the prevalence of BRCA1/2 mutations among women with breast cancer (BC) is ...

A family history of breast cancer will not predict female early onset breast cancer in a population-based setting [PDF]

open access: yes, 2008
: BACKGROUND: An increased risk of breast cancer for relatives of breast cancer patients has been demonstrated in many studies, and having a relative diagnosed with breast cancer at an early age is an indication for breast cancer screening.

Allele-specific expression mediates primary resistance to poly (ADP-ribose) polymerase inhibitor therapy in a case of double-germline mutant gastric cancer

open access: yesJournal of International Medical Research, 2020
Breast cancer gene 1 and 2 ( BRCA1 and BRCA2 ) are human tumor suppressor genes. BRCA mutations increase the risk for breast, ovarian, and gastric cancer.

BRCA1 regulates p53-dependent gene expression [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
Mutations in BRCA1 are present in 45% of families that segregate with susceptibility for breast cancer and in 80–90% of families with both breast and ovarian cancer. Here we report that BRCA1 stimulates artificial and genomic promoter constructs containing p53-responsive elements.

Patients with pathogenic variants for breast cancer other than BRCA1 and BRCA2: qualitative interviews about health care experiences

open access: yesHereditary Cancer in Clinical Practice, 2019
Background Genetic testing for hereditary cancer syndromes has been revolutionized by next-generation sequencing, which allows for simultaneous review of numerous genes.

Prevalence of BRCA1 mutations in familial and sporadic greek ovarian cancer cases.

open access: yesPLoS ONE, 2013
Germline mutations in the BRCA1 and BRCA2 genes contribute to approximately 18% of hereditary ovarian cancers conferring an estimated lifetime risk from 15% to 50%.

A de novo complete BRCA1 gene deletion identified in a Spanish woman with early bilateral breast cancer

open access: yesBMC Medical Genetics, 2011
Background Germline mutations in either of the two tumor-suppressor genes, BRCA1 and BRCA2, account for a significant proportion of hereditary breast and ovarian cancer cases.
