Breast Cancer    BRCA1 & BRCA2 Gene Mutations HD
www.elarasystems.com October is breast cancer awareness month, and while most people are aware of breast cancer, they may be unaware of certain factors which increase the risk of developing the disease. Individuals with a strong family history of breast cancer may choose to receive a gene test to assess these risks. A gene test looks for specific mutations in your BRCA1 or BRCA2 gene. A mutation in these genes can be inherited from either your mother or your father. BRCA1 and BRCA2 help control normal cell growth. Mutations in these genes may increase the risk of developing breast cancer. According to the National Cancer Institute: About 12% of women in the general population will develop breast cancer. However, about 45% of women who have inherited a BRCA2 mutation will develop breast cancer, and about 55-65% of women with a BRCA1 mutations will develop breast cancer. Consider putting together an early detection plan and be proactive about your health.

BRCA mutation
This breast cancer lecture explains about the brca gene (brca1 and brca2 mechanism) mutation which leads to the development of breast cancer. A BRCA mutation is a mutation in both of the genes BRCA1 and BRCA2. Detrimental mutations in these tumor suppressor genes produce a hereditary breast-ovarian melanoma syndrome in affected families. Mutations in BRCA1 and BRCA2 are distinctive, and breast cancer is relatively original, so these mutations consequently account for only five to ten percent of all breast cancer cases in women. 1000s of distinctive types of mutations in these genes have been recognized. Excessive-danger mutations, which disable an primary error-free DNA repair procedure (homology directed repair), tremendously develop the character's threat of setting up breast cancer, ovarian melanoma and specific different cancers. Why BRCA1 and BRCA2 mutations lead preferentially to cancers of the breast and ovary is not identified, but lack of BRCA1 function seems to result in non-useful x-chromosome inactivation. No longer all mutations are excessive-chance; some show up to be harmless editions. The cancer hazard related to any given mutation varies greatly and depends on the distinctive variety and area of the mutation and in all probability different person reasons. Ladies with unsafe mutations in either BRCA1 or BRCA2 have risk of breast melanoma that is about five occasions the average chance, and a hazard of ovarian cancer that's about ten to thirty occasions common. BRCA1 mutations typically confer a higher danger of breast and ovarian melanoma in females than BRCA2 mutations. Having a high-threat mutation does no longer guarantee that the girl will increase any sort of cancer, or warranty that any melanoma that appears was once genuinely induced through the mutation, alternatively than every other element, like alcohol consumption.

Chromosome 13 - BRCA2 and DNA Damage
EXPLORE THE RI ADVENT CALENDAR: http://rigb.org.uk/advent Mistakes in the "recipe" of your DNA -- if bits of code go missing, or get swapped or damaged -- could spell the difference between life and death. DNA often gets damaged by everyday processes within our bodies, but also from external factors such as UV radiation or tobacco smoke. Luckily, our bodies are well equipped to fix this damage thanks, in part, to the BRCA2 gene, found on chromosome 13. BRCA2 encodes for a large protein which carries out repair work on damaged DNA. It's no surprise then that if the BRCA2 is faulty, or missing, our cells can't repair themselves properly. As a result, the damaged DNA builds up and this can lead to cancer. In turns out, however, that faults on BRCA2 aren't necessarily such an advantage to cancer cells. As their BRCA2 gene is faulty, the only remaining "tool" in a cancer cell's molecular repair kit is another gene known as PARP. Dr Kat Arney from Cancer Research UK explains how by using drugs to block PARP function, scientists are hoping to prevent cancer cells from repairing themselves, causing them to die off. Whilst developing cancer treatments is certainly no piece of cake, drugs with PARP inhibitors are already showing great promise in trials. You can find out more about research into PARP inhibitors on the Cancer Research UK science blog at the following links: http://scienceblog.cancerresearchuk.org/2008/07/10/a-%E2%80%98lethal-weapon%E2%80%99-in-the-search-for-new-cancer-treatments/ http://scienceblog.cancerresearchuk.org/2011/07/12/widening-the-net-for-parp-inhibitors/ For more information on related cancer research visit: www.cruk.org With thanks to BBSRC: http://bbsrc.ac.uk/ Don't miss the 2013 CHRISTMAS LECTURES on BBC Four and BBC iPlayer: http://rigb.org/christmas-lectures The Ri is on Twitter: http://twitter.com/ri_science and Facebook: http://www.facebook.com/royalinstitution and Tumblr: http://ri-science.tumblr.com/ Our editorial policy: http://www.rigb.org/home/editorial-policy Subscribe for the latest science videos: http://bit.ly/RiNewsletter

This DNA Scan Lets Parent Know If Their Newborn Has An Incurable Disease (HBO)
DNA tests for newborns to check for diseases are already mandated across the U.S., but a new study at Boston's Brigham and Women's hospital called "BabySeq" is taking it a step further. This landmark genetic scan screens newborns for around 1,800 diseases including breast cancer and genetic mutations that produce sudden cardiac death — which leads to another main component of the study: parents that choose to know these results. The National Institutes of Health funds the BabySeq study at about $25 million. The initial round of results from the study, will help doctors determine how to use the testing in the future, and also measure the psychological and economic impact these results might have on the parents and newborns that receive this information. After babies are born, researchers from the project go into delivery rooms to get parents on board, but so far they’ve had trouble getting them to participate. BabySeq says that 9 out of 10 parents they asked denied doing the test. VICE News found one family that did, and followed them on the day of their test results for their newborn son, Bo.

The spectrum of breast cancer susceptibility genes: Professor Georgia Chenevix-Trench
In this talk from Science at the Shine Dome 2014 Professor Georgia Chenevix-Trench discusses the spectrum of breast cancer susceptibility genes. Breast cancer was the first common, complex disease for which a highly penetrant predisposition gene was mapped to a chromosomal location. This was followed rapidly, in the 1990s, by the identifi cation of the BRCA1 and BRCA2 genes, rare mutations which account for about one third of multiple-case breast (and ovarian) cancer families. Since that time, we and others have identified a small number of genes, mostly involved in double strand DNA repair and including ATM, in which uncommon mutations show moderate penetrance. However, since the advent of genome-wide association studies we have identifi ed more than 100 common genetic polymorphisms associated with small increased risk of breast cancer, some of which also modify the risk of breast cancer in women with mutations in BRCA1 and BRCA2. The great challenge is now to find the causal variants at these loci, and determine the mechanisms underlying their association with breast cancer risk. Most of the causal variants appear to lie in regulatory regions, and affect the expression of one or more genes in the vicinity, some of which might provide the key for the development of novel risk reduction medications.

Genetic variants that modify breast cancer risk in women who carry a BRCA2 mutation:
Darwin Lunchtime Lectures by Karoline Kuchenbaecker Women carrying a pathogenic mutation in the BRCA2 gene have an increased risk of breast cancer. However, risk varies considerably between affected families. Our aim was to understand why risk can differ and what the predictors are. Our approach focused on other genetic variants that modify breast cancer risk We tried to identify some of these by comparing a large number of genetic variants in 4,330 BRCA2 mutation carriers with breast cancer and in 3,881 without. We analysed whether carrying a certain allele of a genetic variant was associated with increased or decreased likelihood of developing cancer. A variant on chromosome 6 was significantly associated with risk of cancer. Those who carried the minor allele of this variant had a 25% decreased risk of breast cancer. Risk predictors can be used to derive refined risk estimates for individuals carrying a BRCA2 mutation. These estimates are crucial in clinical management which can include decisions regarding preventive treatments. Furthermore, identification of genetic risk modifiers could help us improve our understanding of the biology of breast cancer development in these women.

FISH Analysis of ESR1 Amplification in Breast Cancer - A Video Illustration
Analysis of estrogen receptor alpha gene (ESR1) amplification detected by fluorescent in situ hybridization (FISH) in breast cancer: The ESR1 FISH probe (ZytoVsion GmbH, Bremerhaven, Germany) is labeled with a "SpectrumGreen" fluorochrome. Gene signals appear as green pinhead shaped dots. For copy number reference a chromosome enumeration probe for centromere of Chromosome 6 (CEP6) is labeled with a "SpectrumOrange" fluorochrome. CEP6 signals appear as orange pinhead shaped dots. Nuclei are counterstained with 4',6-diamino-2-phenylindole (DAPI). Nuclear chromatin DNA is appearing in blue color. The video clip was taken using an Olympus IX51 microscope at 100× magnification, an Olympus XM10 digital camera (1,376 × 1,032 pixels) and Olympus cellSens imaging software. Analysis starts with microscope fluorescence filter setting for fluorochrome "SpectrumGreen": Distribution of FISH signals over cell nuclei of tissues can mostly be estimated for a first sight screening in the fluorescence filter spectrum of the gene probe fluorochrome. Signals in full z-axis are taken into account. Filter change to "SpectrumOrange": Signals of the centromere reference, the chromosome enumeration probe (CEP), are checked for signal quality. Filter change to "SpectrumGreen": An area with nuclei showing distinguishable gene signals respectively signal cluster (e.g. signal cluster marked by white arrow in minute 01:27) is selected to determine copy number. Signals in full z-axis are taken into account. Filter change to "SpectrumOrange": Signals of the centromere reference, the chromosome enumeration probe (CEP), are checked for signal quality. Signals in full z-axis are taken into account. Filter change to DAPI (blue): Chromatin stained nuclei are checked. Sufficient integer and separable nuclei are selected to determine gene and centromere copy number. Full z-axis is taken into account. It has also to be taken into account, that a complete integrity of nuclei can not be expected or guaranteed for most nuclei analzyed, since a risk of truncation of nuclei due to tissue slide preparation, is always given in 4µm tissue sections. Filter change to "SpectrumGreen": Gene signals are counted. The three dimensional constitution of the nucleus is taken into account by a variable adjustment of optical z-axis layer.

Voluntary Mastectomy Is Not Necessary
Voluntary Mastectomy Is Not Necessary http://drthomaslodi.com Is a voluntary mastectomy necessary as a preventative against getting breast cancer? The answer is no, it is absolutely not needed. In fact, it is an unnecessary mutilation of the body that should never happen. Far too many women are misled and that needs to change. A thorough understanding on the subject and sharing that knowledge with as many people as possible will help spread the word. Let’s go for a minute with the argument that if someone had this certain gene or genetic disposition that made them susceptible to getting breast or ovarian cancer. So, you go ahead and remove your breasts, ovaries and uterus as a result. Now you’re thinking you have safeguarded yourself from breast and ovarian cancer, however, you are now at the same risk for getting pancreatic and colon cancer. And, you can’t remove your pancreas or your colon as you need those to live. BRCA stands for BReast CAncer susceptibility gene. There is a repair mechanism for broken double stranded DNA. All DNA is double stranded. When there is a flawed repair mechanism that is what is called the BRCA gene. We all, both men and women have BRCA genes and some are flawed and some are not. This gene can be inherited from your mother or your father and it can pass to the son or the daughter. There are two chromosomes for every gene so even if you inherit one defective chromosome, the other chromosome still has to have enough toxification to make it a fully defective repair mechanism for double stranded DNA. This is very difficult to do and should not be feared. Even if you removed the body parts we mentioned above, you still have to do what you should have done in the first place, eat healthy, go to sleep early, etc. so that you are not helping to produce cancer. Keep in mind, removing an organ doesn’t mean you are immune from that particular cancer. https://www.youtube.com/playlist?list=PLKTjY73tu_1-rfj4CHe8A42Ccw4_iZgL6 https://www.youtube.com/channel/UCYu61175aI-xV-U4_vtGE5A/videos

Understanding BRCA Mutations and Risk
BRCA1 and BRCA2 are breast cancer gene mutations. When a mutation occurs, the gene doesn’t function properly, DNA errors don’t get repaired, and the risk of cancer increases. A genetic counselor will review your family histories, discuss the testing process, and explain benefits as well as the risks of learning about a genetic mutation that may increase your cancer risk.
Some Genes May Offer Cancer Protection
Evaluating the risk people have of getting cancer based on their genetic attributes has given rise to the idea of someone who is protected from getting cancer based on their genes. Most studies focus on what gene variants give people a higher risk of cancer, and finding people with a lower risk is a challenge, because if they are healthy, they won't come in for testing. In an ongoing search for the cure, scientists are examining cancer from new viewpoints. One is that people, who have a predisposition to the disease but do not develop it, may possess genetic traits that offer them some form of protection. Most studies focus on what gene variants give people a higher risk of cancer, and finding people with a lower risk is a challenge, because if they are healthy, they won't come in for testing. One way around this limitation is to identify the protective gene variants by comparing the genetic sequences of people who have cancer and people who don't but have similar ages and risk factors. In 2004, researchers from the University of Sheffield studying gene variation in relationship to breast cancer and programmed cell death found that women subjects who inherited a gene variant called D302H in the CASP8 gene had a lower risk of developing breast cancer. Subsequent studies have found that this variant also lowers the risk of prostate and other cancers. Another study linked one of the variants in part of the telomerase enzyme to longer chromosome caps and a decreased risk of some kinds of breast cancer.

Genetic Mutation Animation from In the Family
In the Family is a documentary film about predicting breast and ovarian cancer, the consequences of knowing, and the women who live with the risk. Beginning with her story of testing positive for the familial breast cancer mutation (BRCA), Filmmaker Joanna Rudnick chronicles the lives of several women currently undergoing the process of genetic testing following them from their decision to seek testing, through the testing process, and in the aftermath when they are coming to terms with the information they receive. These stories of the first generation of women to live with the knowledge that they are predisposed to a life-threatening disease will teach us what it means to survive a diagnosis of high risk without being consumed or defined by it. They will help us to understand the psychological, legal, ethical, cultural and social complexities of genetic testing for a mutation, which affects the entire family, for which there is no cure, and wherein the only treatments currently available involve enormous quality-of-life sacrifices.

CACRM - BRCA1 and BRCA2: Cancer Risk and Genetic Testing
Because harmful BRCA1 and BRCA2 gene mutations are relatively rare in the general population, most experts agree that mutation testing of individuals who do not have cancer should be performed only when the person’s family history suggests the possible presence of a harmful mutation in BRCA1 or BRCA2. There are options for Couples with known BRCA 1 and BRCA 2 genes: PGD is one of them.

CHEK2 - Medical Meaning
https://word2speech.com/medical/ CHEK2 CHEK2: A gene on chromosome 22q that encodes a kinase enzyme and influences a person's susceptibility to breast cancer. A variant (allele) of CHEK2 that abolishes its kinase activity results in a 2-fold increase in the risk of breast cancer for women and a 10-fold increase in risk for men. The CHEK2 kinase is at a checkpoint in the cell cycle, is activated in response to DNA damage, and prevents the damaged cell from entering mitosis.

BRCA across tumour types
In this video, Judith Balmaña addresses the role of the BRCA1 and BRCA2 proteins in cancer risk assessment, early detection and cancer prevention, and the implication of BRCA deficiency as a predictive biomarker for targeted therapies in different tumour types. BRCA1 and BRCA2 encode two large proteins, which localize to the cell nucleus and are widely expressed in different tissues during the S and G2 phases. These proteins work to preserve chromosome stability, mainly through DNA repair, cell cycle control, and fork stabilization during replication. BRCA1 is a pleiotropic DNA damage repair protein that functions in both checkpoint activation and DNA repair. BRCA1 links DNA damaging sensing and DNA damage repair effectors. BRCA2 is a mediator of the core mechanism of homologous recombination repair, responsible for error-free repair of double DNA strand breaks. Inactivation of either of the two proteins leads to carcinogenesis. Germline mutations in these genes are relatively rare. It is estimated that their prevalence in the population is 1 out of 200-400 individuals, so 0.25%. This prevalence is higher in certain groups, such as individuals of Ashkenazi ancestry, where the prevalence is 1 out 40 individuals, or 2.5%, due to three founder mutations. In unselected women with breast cancer, germline mutations in these genes are observed in 2-5%. This frequency is higher in women with triple negative breast cancer, or those of young onset, or with a family history. Between 8-18% of women with invasive epithelial non-mucinous ovarian cancer might have a germline BRCA1 or BRCA2 mutation. In pancreatic ductal adenocarcinoma, their frequency is 2-4%, and in prostate cancer the prevalence ranges from 1-2% if young onset or localised, to 4-6% among metastatic prostate cancer patients. The cumulative risk of breast cancer in BRCA1 carriers is 40% at age 50, and 72% at age 80. The cumulative risk of breast cancer in BRCA2 carriers is around 35% at age 50, and 68% at age 80. Cumulative ovarian cancer risk is almost 40% for BRCA1 carriers, and almost 20% for BRCA2 carriers. The cumulative risk of pancreatic cancer, mainly in BRCA2 carriers, is between 1.5% and 3%, and that of prostate cancer, also mainly in BRCA2 carriers, is between 5% and 15%. These prostate tumours typically present earlier, with a more aggressive phenotype and a reduced survival than sporadic cancer. Early detection of ovarian cancer still remains a challenge. Risk reducing bilateral salpingoophorectomy is recommended, usually around age 40, and around age 45 in BRCA2 carriers. In mutation carriers, this intervention has been associated with an ovarian cancer risk reduction of 80-95% and a mortality reduction. Salpingectomy alone is a surgical procedure that is potentially as efficient as salpingoophorectomy, but it is still considered to be an investigational approach. Prophylactic mastectomy has also been associated with a 90% or more breast cancer risk reduction and it is an option to individualise in women with a BRCA mutation. Regarding surveillance options, women are recommended to undergo breast MRI from the age of 25, and add a mammogram at age 30, on a yearly basis. CA125 levels with transvaginal ultrasound every 6 months might be considered in women until the decision on prophylactic salpingoophorectomy. In men, prostate cancer screening is recommended from the age of 40-45 years. Cancer cells with BRCA mutations lead to homologous recombination repair deficiency and are more sensitive to DNA damaging agents, such as platinum agents or PARP inhibitors. Indeed, platinum-based regimens have shown higher efficacy in patients with advanced breast, ovarian, and pancreatic tumours associated with BRCA-deficiency. PARP inhibitors have been approved for patients with advanced ovarian and breast cancer. In prostate cancer, a breakthrough designation by FDA has been granted; and in pancreatic cancer, clinical trials are currently ongoing. Final take home messages: - Germline testing of BRCA1/2 genes has implications for cancer risk assessment, surveillance/cancer prevention, and targeted therapy. - Individuals with a germline BRCA1/2 mutation have an increased risk of breast cancer, ovarian cancer, pancreatic cancer, male breast cancer, prostate cancer. - Surveillance recommendations and risk reduction surgeries are invidualised in patients with a germline BRCA1/2 mutation. - BRCA1/2 mutations may cause homologous recombination deficiency and serve as a predictive biomarker for targeted therapies, such as platinum and PARP, among others. - Mainstream BRCA genetic testing for therapeutic indications will likely increase the number of mutation carriers identified and represent an opportunity for cascade testing in relatives who may benefit from individualised surveillance and prevention programmes.

Breast Cancer Genes Related to Fertility -- Ken Smith, PhD, Saundra Buys, MD, and Geri Mineau, PhD
Ken Smith, PhD, along with fellow HCI investigators and co-authors Geri Mineau, PhD, and Saundra Buys, MD, set out to examine the idea that increased fertility might be a potential advantage in BRCA mutations. Doctoral student Heidi Hanson was also a critical collaborator on the research team. Using information collected from the Utah Population Database (UPDB), they looked at patterns of both childbearing and early death in two groups of women with BRCA1/2 mutations representing two eras. They also looked at control groups who did not carry the mutation. One BRCA group consisted of women born before 1930, who would have completed their childbearing years before birth control was readily available and reliable. The other BRCA group was women from later generations who had access to effective birth control.

3.4 Loss of heterozygosity (LOH)
Mitotic recombination may contribute to Rb is inactivation Recombination between chromosomes was known to occur almost exclusively during meiosis. What about mitotic recombination between: one of the chromatid arms carrying the wild- type Rb allele and one carrying the mutant allele one is of paternal origin the other of maternal origin Mitotic recombination the chromosomes would both remain full-length and indistinguishable from the chromosomes that existed prior to this genetic exchange. (unlike the chromosomal translocations of Burkitt’s lymphoma during meiosis) Loss of heterozygosity (LOH) Mitotic recombination was found to occur at a frequency of up to 10-4 per cell generation. This is a far easier way for a cell to rid itself of the remaining wild-type copy of the Rb gene than mutational inactivation Following the mitotic recombination they lose heterozygosity and become homozygous. Gene Conversion can achieve LOH. A DNA strand being elongated during DNA replication on one chromosome will form a hybrid with the complementary DNA strand present in the second, homologous chromosome. this newly synthesized strand of DNA will acquire DNA sequences from a stretch of the paired chromosome. Such gene conversion is known to occur even more frequently per cell generation than does mitotic recombination. Evidence of LOH Retinoblastoma tumor cells were predicted to show LOH at the Rb locus i.e. the same mutation on both chromosomes Only a small minority were predicted to carry two distinct, mutant alleles of Rb, (each inactivated by an independent mutational event)
