2. This study comprehensively describes the characteristics of the 1,650 unique BRCA1 and 1,731 unique BRCA2 deleterious (disease-associated) mutations identified in the CIMBA database.

3. Study shows that BRCA1, PALB2 and BRCA2 can all play a significant role in both checkpoint activation and checkpoint maintenance, depending on cell type and context, and that PALB2 links BRCA1 and BRCA2 in the checkpoint response. The BRCA1-PALB2 interaction can be important for checkpoint activation, whereas PALB2-BRCA2 complex appears to be more critical for checkpoint maintenance.

4. Our results did not provide evidence for elevated risks of invasivebreast cancer (BC) or epithelial ovarian cancer in BRCA1/BRCA2 predictive test negatives

13. 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.

14. 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.

15. 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.

16. 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.

17. Identified two BRCA2 variants of unknown significance.

18. 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

19. 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.

20. 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.

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

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.

3. DNA repair by homologous recombination is dramatically decreased in CG30169 (brca2 homolog) mutants.

1. the data suggest for the first time that brca2/fancd1 is essential for vertebrate kidney ontogeny.

2. Carcinogenesis in zebrafish with combined mutations in tp53 and brca2 typically requires biallelic mutation or loss of at least one of these genes.

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 .

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
