A Novel Breast Cancer ^ Associated BRIP1 (FANCJ/BACH1) Germ- Line Mutation Impairs Protein Stability and Function
Cancer Prevention and Susceptibility A Novel Breast Cancer ^ Associated BRIP1 (FANCJ/BACH1)Germ- line Mutation Impairs Protein Stability and Function Arcangela De Nicolo,1MariellaTancredi,4 Grazia Lombardi,4 Cristina Chantal Flemma,4 Serena Barbuti,4 Claudio Di Cristofano,4 Bijan Sobhian,1Generoso Bevilacqua,4 Ronny Drapkin,2,3 andMariaAdelaideCaligo4 Abstract Purpose: BRCA1-interacting protein 1 (BRIP1; FANCJ/BACH1), which encodes a DNA helicase that interacts with BRCA1, has been suggested to be a low-penetrance breast cancer predispos- ing gene.We aimed to assess whether BRIP1 mutations contribute to breast cancer susceptibility in our population and, if so, to investigate the effect of such mutation(s) on BRIP1function. Experimental Design: A series of49 breast/ovarian cancer families, devoid ofa BRCA1/ BRCA2 mutation, were screened for BRIP1 mutations. Functional analyses, including coimmuno- precipitation and stability assays, were employed to further characterize a previously unreported variant. Results: Five sequence alterations were identified, of which four had been already described. Herein, we report a novel BRIP1 germ-line mutation identified in a woman with early-onset breast cancer. The mutation consists ofa 4-nucleotide deletion (c.2992-2995delAAGA) in BRIP1 exon 20 that causes a shift in the reading frame, disrupts the BRCA1-binding domain of BRIP1, and creates a premature stop codon. Functional analysis ofthe recombinant mutant protein in transfected cells showed that the truncation interferes with the stability of the protein and with its ability to interact with BRCA1. Loss ofthe wild-type BRIP1 allele with retention ofthe mutated one was observed in the patient’s breast tumor tissue. Conclusions: These results, by showing that the newly identified BRIP1 c.2992-2995delAAGA mutation is associated with instability and functional impairment of the encoded protein, provide further evidence of a breast cancer ^ related role for BRIP1. -

Primary Screening for Breast Cancer with Conventional Mammography: Clinical Summary
Primary Screening for Breast Cancer With Conventional Mammography: Clinical Summary Population Women aged 40 to 49 y Women aged 50 to 74 y Women aged ≥75 y The decision to start screening should be No recommendation. Recommendation Screen every 2 years. an individual one. Grade: I statement Grade: B Grade: C (insufficient evidence) These recommendations apply to asymptomatic women aged ≥40 y who do not have preexisting breast cancer or a previously diagnosed high-risk breast lesion and who are not at high risk for breast cancer because of a known underlying genetic mutation Risk Assessment (such as a BRCA1 or BRCA2 gene mutation or other familial breast cancer syndrome) or a history of chest radiation at a young age. Increasing age is the most important risk factor for most women. Conventional digital mammography has essentially replaced film mammography as the primary method for breast cancer screening Screening Tests in the United States. Conventional digital screening mammography has about the same diagnostic accuracy as film overall, although digital screening seems to have comparatively higher sensitivity but the same or lower specificity in women age <50 y. For women who are at average risk for breast cancer, most of the benefit of mammography results from biennial screening during Starting and ages 50 to 74 y. While screening mammography in women aged 40 to 49 y may reduce the risk for breast cancer death, the Stopping Ages number of deaths averted is smaller than that in older women and the number of false-positive results and unnecessary biopsies is larger. The balance of benefits and harms is likely to improve as women move from their early to late 40s. -
Review of Cancer Genetics
Review of Cancer Genetics Genes are pieces of information in the cells that make up the body. Cells are the basic units of life. Normally, cells grow, divide and make more cells in a controlled way as the body needs them to stay healthy. Cancer happens when a cell grows out of control in an abnormal way. All cancer is caused by a buildup of mutations (changes) in specific genes. Normally, these genes help the cell grow and divide in a controlled manner. The mutation in the gene damages this process and, as a result, the cell can grow out of control and become cancer. In most people who have cancer, the gene mutations that lead to their cancer cannot be passed on to their children. However, some families have a gene mutation that can get passed on from one generation to another. The differences between sporadic (non-hereditary) and hereditary forms of cancer are reviewed below. Additionally, some families have more cancer than would be expected by chance, but the cancer does not seem to be hereditary. This “familial” form of cancer is also discussed below. Sporadic Cancer Most cancer – 75% to 80% – is sporadic. In sporadic cancer, the gene mutations that cause the cancer are acquired (occur only in the tumor cells) and are not inherited. Risk for acquired gene mutations increases with age and is often influenced by environmental, lifestyle or medical factors. Cancer can sometimes happen by chance. Everyone has some risk of developing cancer in his or her lifetime. Because cancer is common, it is possible for a family to have more than one member who has cancer by chance. -

BRCA1 and BRCA2 Full Gene Sequence Analysis and Common Deletion/Duplication Variants
BRCA1 and BRCA2 Full Gene Sequence Analysis and Common Deletion/Duplication Variants Testing includes full gene sequencing of exons and 25 base pairs of introns of BRCA 1 and 2 and the common deletions of BRCA1 (exon 13 del 3.835kb, exon 13 dup 6kb, exon 14-20 del 26kb, exon 22 del 510bp, exon 8-9 del 7.1kb). Sequencing does not include the promoter, enhancers or splicing modulators in intronic regions. Deletion duplication analysis is limited to the commonly reported variants; refer to full deletion/duplication testing. Indication: This testing is indicated for individuals that meet the criteria for Hereditary Breast and Ovarian Cancer listed in the National Comprehensive Cancer Network (NCCN) guidelines. For assistance with interpreting guidelines, please contact Henry Ford Precision Genomic Diagnostics, or refer to genetic counseling for evaluation. Testing on minors is not indicated. BRCA1 and BRCA2 are genes that code for proteins that help repair DNA damage. Inherited mutations in BRCA 1 or 2, in combination with additional acquired mutations, can result in increased risk for developing cancer. Specific mutations in BRCA1 and BRCA2 increase the risk of breast and ovarian cancers, and have been associated with increased risk of several additional types of cancer. BRCA1 and BRCA2 mutations account for about 20 to 25 percent of hereditary breast cancers and about 5 to 10 percent of all breast cancers. In addition, BRCA1 and BRCA2 account for about 15 percent of ovarian cancers overall. Breast and ovarian cancers associated with BRCA1 and BRCA2 mutations tend to develop at younger ages than their nonhereditary counterparts. -
NBN Gene Analysis and It's Impact on Breast Cancer
Journal of Medical Systems (2019) 43: 270 https://doi.org/10.1007/s10916-019-1328-z IMAGE & SIGNAL PROCESSING NBN Gene Analysis and it’s Impact on Breast Cancer P. Nithya1 & A. ChandraSekar1 Received: 8 March 2019 /Accepted: 7 May 2019 /Published online: 5 July 2019 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Single Nucleotide Polymorphism (SNP) researches have become essential in finding out the congenital relationship of structural deviations with quantitative traits, heritable diseases and physical responsiveness to different medicines. NBN is a protein coding gene (Breast Cancer); Nibrin is used to fix and rebuild the body from damages caused because of strand breaks (both singular and double) associated with protein nibrin. NBN gene was retrieved from dbSNP/NCBI database and investigated using computational SNP analysis tools. The encrypted region in SNPs (exonal SNPs) were analyzed using software tools, SIFT, Provean, Polyphen, INPS, SNAP and Phd-SNP. The 3’ends of SNPs in un-translated region were also investigated to determine the impact of binding. The association of NBN gene polymorphism leads to several diseases was studied. Four SNPs were predicted to be highly damaged in coding regions which are responsible for the diseases such as, Aplastic Anemia, Nijmegan breakage syndrome, Microsephaly normal intelligence, immune deficiency and hereditary cancer predisposing syndrome (clivar). The present study will be helpful in finding the suitable drugs in future for various diseases especially for breast cancer. Keywords NBN . Single nucleotide polymorphism . Double strand breaks . nsSNP . Associated diseases Introduction NBN has a more complex structure due to its interaction with large proteins formed from the ATM gene which is NBN (Nibrin) is a protein coding gene, it is also known as highly essential in identifying damaged strands of DNA NBS1, Cell cycle regulatory Protein P95, is situated on and facilitating their repair [1].
