Human Breast Cancer 2, Early Onset (BRCA2) interaction partners

1. the study included all BRCA1/2 germline missense mutations identified in breast and ovarian cancer patients; the Asian population was the most affected by BRCA2 mutant patterns (Systematic Review)

2. Applying established referral criteria for genetic testing in Serbia will help identify BRCA1/2 mutation carriers but will not help identify mutations in other cancer susceptibility genes. Until better predictors emerge we should be performing wider genetic testing of EOC in order to identify all mutation carriers.

3. In adjusted analysis, age >/=80 years (odds ratio [OR] 0.10; P = 0.002), psychiatric disorders (OR 0.46; P = 0.006), occupation requiring at least 3 years of university or college education (OR 2.03; P = 0.003), and breast cancer or ovarian cancer in first-degree or second-degree relatives (OR 1.66; P = 0.02) were independently associated with uptake of BRCA1/2 testing.

4. Despite calls for BRCA1/2 population screening, there remains a critical need to identify those most at risk who should receive cancer genetics services. B-RSTtrade mark version 3.0 demonstrates high sensitivity for BRCA1/2 mutations, yet remains a simple and quick screening tool for at-risk individuals.

5. The recalibrated algorithms and new metapredictors significantly improved upon current models for predicting the impact of variants in cancer risk-associated domains of BRCA1 and BRCA2. Prediction of the functional impact of all possible variants in BRCA1 and BRCA2 provides important information about the clinical relevance of variants in these genes.

6. Identified two BRCA2 variants of unknown significance.

7. Neoadjuvant versus adjuvant with standard anthracycline- and taxane-containing regimens results in similar disease-free survival and overall survival among patients with stage I and II triple-negative breast cancer regardless of BRCA status

8. Our findings indicate that in the Indian population, there is a high prevalence of mutations in the high-risk breast cancer genes: BRCA1, BRCA2, TP53, and PALB2.

9. BRCA1/2 mutation status leads to better responses to neoadjuvant chemotherapy in breast cancer. Pathological complete response is the main predictor of disease-free survival and overall survival, independently of BRCA1/2 mutation status.

10. Eligible patients for this study were healthy women with >/= 17% lifetime risk of breast cancer or with a mutation in BRCA1 or BRCA2. A total of 632 women were screened between 2002 and 2012 (each for 6 years). During the study, 30 women were diagnosed with breast cancer, with 10 of these diagnoses occurring between screening visits, and six of the 10 diagnosed women were gene carriers

11. Among BRCA1/2 mutation wild-type patients, homologous recombination (HR) deficient(HRD) patients were more likely to achieve a pathologic complete response (OR 16, 95% CI 1.65-160.41, p = 0.0041) compared with HR non-deficient patients. Further, HRD scores were highly concordant pre- and post-therapy

12. these results provide a significant insight into certain mutations and proteins involved in the interaction network of BRCA1 and BRCA2, which may have common roles in breast cancer and ovarian cancer.

13. The overall frequencies of the BRCA germline mutations (BRCA1 and BRCA2 )were 10.2% in breast and 30.7% in ovarian cancer patients. These data shed new light into the prevalence of BRCA mutations in the Arab women population.

14. This study provides a comprehensive view of known and novel BRCA1/2 mutations in breast cancer (BC)patients from the Republic of Macedonia and contributes to the global spectrum of BRCA1/2 mutations in breast cancer

15. Our findings, using the largest gene panel for Male breast cancer (MBC) patients so far, indicate that BRCA testing (BRCA1 and BRCA2)should be the primary concern for MBC patients.

16. association between family history (FH) of Breast cancer(BC) and ovarian cancer(OC) risks was slightly smaller in magnitude (HR: 0.85, 95% CI: 0.55-1.30; HR: 0.64, 95% CI: 0.34-1.21 for BC-only FH in BRCA1 and BRCA2, respectively; HR: 1.46, 95% CI: 0.80-2.68; HR: 1.49, 95% CI: 0.44-4.02 for OC-only FH in BRCA1 and BRCA2, respectively), indicating that mutation position explains only part of the association.

17. This study reports familial communication in a BRCA1/BRCA2 screening setting... This suggests that universal BRCA screening does not differentially affect communication or the use of familial genetic information

18. The study of BRCA1/2 gene in Southern Mediterranean countries revealed low penetrance recurrent mutations in sporadic and familial breast cancer.

19. Results identified a novel large BRCA2 deletion in 0.9% of the screened Colombian families in addition to 6310delGA and the recurrent 1991del4 mutations. Among unselected breast cancer cases, 1.1% tested positive for BRCA2/3034del4, and 0.4% for BRCA2/1991del4.

20. our study provides novel data on ovarian BRCA1/2 mutation prevalence worldwide, enhances adequate patient selection for family counseling and prevention, and sheds light on the benefits of iPARP treatment.

Fruit Fly (Drosophila melanogaster) Breast Cancer 2, Early Onset (BRCA2) interaction partners

1. persistent meiotic DNA double-strand breaks might correspond to crossovers, which are mobilized to the nuclear envelope for their repair; Brca2-Pds5 complexes may be key mediators of this process.

2. A mutation in Cyp6d2, a cytochrome P450 gene, when combined with a brca2 mutation, resulted in synergistic hypersensitivity to camptothecin.

Mouse (Murine) Breast Cancer 2, Early Onset (BRCA2) interaction partners

1. BRCA2-proficient and deficient cells are radiosensitised by HT, indicating that HT does not exclusively act by inhibition of HR.

2. Results suggest that the greater reliance on homology-directed repair (HDR) in the proliferating mammary gland, rather than a specific dependence on breast cancer 2 protein (BRCA2), may increase its susceptibility to tumorigenesis incurred by BRCA2 mutation.

3. The functional consequence of Parp1 heterozygosity on BRCA2 loss is demonstrated by a significant increase in tumorigenesis in Brca2 knockout mice.

4. Data indicate the importance of breast cancer 1 protein (BRCA1)/breast cancer 2 protein (BRCA2) function in cranial neural crest cells (CNCCs) during craniofacial skeletal formation.

5. we generated a Brca2 knock-in mouse model lacking exons 4-7 and demonstrated that these exons are dispensable for viability as well as tumor-free survival. This study provides the first in vivo evidence of the functional significance of a minor transcript of BRCA2 that can play a major role in the survival of humans who are homozygous for a clearly pathogenic mutation.

6. we describe a genetic approach to examine the functional significance of the interaction between BRCA2 and PALB2 by generating a knock-in mouse model of Brca2 carrying a single amino acid change (Gly25Arg, Brca2G25R) that disrupts this interaction. In addition, we have combined Brca2G25R homozygosity as well as hemizygosity with Palb2 and Trp53 heterozygosity .

7. Merit40 mutation exacerbated ICL-induced chromosome instability in the context of concomitant Brca2 deficiency but not in conjunction with Fancd2 mutation.

8. Heterozygous and homozygous Brca2 mutation may lead to dysfunction in T cell populations.

9. BRCA2 exon 27 domain maintains chromosomal integrity at both stalled and collapsed replication forks consistent with involvement in both replication fork maintenance and double strand break repair.

15. Results suggest that cellular levels of Brca2 and Rad51 are mutually dependent on each other, and that low levels of these proteins provide selective pressure for reduction of p53, which permits cell growth

16. BRCA2 accumulates DNA damage, which triggers checkpoint signalling and ARF activation

17. data showed that silencing of BRCA2 promoted cell proliferation, migration and invasion in vitro; data reported here demonstrate that BRCA2 may be a promising therapeutic targets for pancreatic ductal adenocarcinoma progression

18. BRCA2 is required for telomere homeostasis and may be particularly important for the replication of G-rich telomeric lagging strands.

19. Loss of Brca2 function predisposes the exocrine pancreas to profound DNA damage, and the frequency of invasive neoplasia is accentuated by the concomitant deregulation of p53
