La proteína BRCA2 (de sus siglas en inglés "Breast Cancer Type 2 susceptibility protein") es una proteína codificada en humanos por el gen BRCA2. [1] Se han identificado ortólogos de BRCA2 [2] en la mayoría de mamíferos para los cuales el genoma completo está disponible.

Standard BRCA1 and BRCA2 tests are used to detect mutations that are known to increase the risk of breast and ovarian cancer development. If a BRCA1 or BRCA2 mutation has been identified in a family member with breast and/or ovarian cancer, then that specific mutation can be tested in other family members to assess their risk. BRCA1 and BRCA2 tests are used to detect pathogenic genetic variants (mutations) that are known to increase the risk of breast and ovarian cancer. These genes are most often tested together. If a BRCA1 or BRCA2 mutation has been identified in a family member with breast and/or ovarian cancer, then that specific mutation can be tested in other family members to assess their risk. 概念・疫学.

BRCA1 and BRCA2 mutation carriers also have an increased lifetime risk of ovarian cancer and, in the absence of reliable early detection and the poor prognosis of ovarian cancer, bilateral salpingo-oophorectomy (BSO) can be offered to these women after completion of childbearing 34,21. Heterozygous mutations of BRCA2 cause susceptibility to breast and ovarian cancer (see OMIM), a phenotype that is not appropriate for our purposes. Homozygous mutations of BRCA2 cause Fanconi anemia (see GeneReviews), which is an appropriate phenotype but is an inappropriate mutational mechanism. 2021-04-08 · Having a BRCA2 mutation is different than BRCA1 mutations (which was what Angelina Jolie had and is spoken of more often) and raises the risk of several different types of cancer.

Individuals with mutations in BRCA2 have a condition called Hereditary Breast and Ovarian Cancer syndrome (HBOC). Women with HBOC have a risk for breast cancer that is greatly increased over the 12.5% lifetime risk for women in the general population of the United States. BRCA2 is a nuclear phosphoprotein that plays an important role in DNA damage repair.

Genetic testing for BRCA1 and BRCA2 mutations cannot detect 100% of these mutations; thus, even with a negative result there is very small chance that there is a BRCA1/BRCA2 gene mutation present that was not identified by the testing method utilized. In addition, there are other genes that may have mutations that can contribute to a family's The mutation profile for high-risk patients was 90.1% sequencing mutations versus 9.9% LRs, and for elective patients, 94.1% sequencing versus 5.9% LRs. This difference may reflect the bias in high-risk patients to carry mutations in BRCA1, which has a higher penetrance and frequency of LRs compared with BRCA2. 2021-03-07 The BRCA2 gene provides instructions for making a protein that acts as a tumor suppressor. Tumor suppressor proteins help prevent cells from growing and dividing too rapidly or in an uncontrolled way.

BRCA2 is a nuclear phosphoprotein that plays an important role in DNA damage repair. As a tumor suppressor gene, loss of BRCA2 protein function leads to genomic instability and malignant transformation (PMID: 21731065).

2021-04-08 · Having a BRCA2 mutation is different than BRCA1 mutations (which was what Angelina Jolie had and is spoken of more often) and raises the risk of several different types of cancer. At the current time, however, our knowledge is still growing and this may change in time. Cancers which are more common in people with BRCA2 mutations include:

Pathogenic variants in the BRCA1 and BRCA2 genes are associated with hereditary breast and ovarian cancer (HBOC) syndrome. The penetrance of BRCA2 was estimated by maximizing the LOD score in BRCA2-mutation families, over all possible penetrance functions. The estimated cumulative risk of breast cancer reached 28% (95% CI 9%-44%) by age 50 years and 84% (95% CI 43%-95%) by age 70 years.
