It has been reported that germline BRCA1 and BRCA2 mutations in ovarian cancer patients tended to be concentrated in certain regions denoted as ovarian cancer cluster region (OCCR). 32 In our series, although mutations in the BRCA1 gene spread over the whole coding region, relatively more mutations occurred within exon 11 as shown in Figure 2. 2014-03-07 Certain variations of the BRCA1 gene lead to an increased risk for breast cancer as part of a hereditary breast–ovarian cancer syndrome.Researchers have identified hundreds of mutations in the BRCA1 gene, many of which are associated with an increased risk of cancer.

Link, Google Scholar: 9. Ovarian cancer (OC) mostly arises sporadically, but a fraction of cases are associated with mutations in BRCA1 and BRCA2 genes. The presence of a BRCA mutation in OC patients has been suggested as a prognostic and predictive factor.

Brca1 brca2 ovarian cancer

BRCA1 is a human tumor suppressor gene (also known as a caretaker gene) and is responsible for repairing DNA. BRCA1 and BRCA2 are unrelated proteins, but both are normally expressed in the cells of breast and other tissue, where they help repair damaged DNA, or destroy cells if DNA cannot be repaired. Hereditary breast and ovarian cancer syndrome (HBOC), caused by a germline pathogenic variant in BRCA1 or BRCA2, is characterised by an increased risk for breast, fallopian tube, primary peritoneal ovarian cancer in females, pancreatic, colorectal cancer, melanoma, prostate and male breast cancer 14,15. Germline mutations in BRCA1 and BRCA2 cause hereditary breast and ovarian cancer. Molecular screening of these two genes in patients with a family history of breast or ovarian cancer has revealed pathogenic variants as well as genetic variants of unknown significance (VUS).

Estimates of these risks vary greatly. By age 70, women who have a BRCA1/2 gene mutation have 45-65 percent chance of getting breast cancer and a 10-70 percent chance of getting ovarian cancer [1-2]. Individuals with a single germline BRCA1 or BRCA2 pathogenic variant have an increased risk for breast (female and male), ovarian, fallopian tube, peritoneal, pancreatic, prostate, melanoma, and other cancers.

Ovarian cancer: About 1.2% of women in the general population will develop ovarian cancer sometime during their lives . By contrast, 39%–44% of women who inherit a harmful BRCA1 variant and 11%–17% of women who inherit a harmful BRCA2 variant will develop ovarian cancer by 70–80 years of age (2–4). Treatment of ovarian cancer in individuals with BRCA1 or BRCA2-related tumours is actually, still similar to sporadic cases, despite some preclinical studies showed that mostly BRCA1 appears to be an important responding factor to DNA damaging–compounds 36. BRCA-positive patients have been reported as associated to: 1.

Enhanced screening for breast cancer can also be undertaken. Normally, the BRCA1 and BRCA2 genes protect you from getting certain cancers. But some mutations in the BRCA1 and BRCA2 genes prevent them from working properly, so that if you inherit one of these mutations, you are more likely to get breast, ovarian, and other cancers. However, not everyone who inherits a BRCA1 or BRCA2 mutation will get breast or ovarian cancer. Everyone has two copies of the BRCA1 and BRCA2 genes, one copy inherited from their mother and Here, we discuss existing knowledge of the role of BRCA1 and BRCA2 mutation in pre-disposition to ovarian cancer. The risk of an individual with a mutation developing cancer of the ovary appears to be influenced by the position of the mutation within the BRCA gene, the presence of allelic variants of modifying genes and the hormonal exposure of the carrier.
