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.

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遺伝子及びBRCA2遺伝子に関連した遺伝性乳がん・卵巣がん症候群 (Hereditary Breast and Ovarian Cancer syndrome: HBOC) は、女性の乳がん・卵巣がん (卵管がんや原発性腹膜がんも含む)、男性の乳がんをはじめとするがんの易罹患性症候群であり、常染色体優性遺伝形式をとる。.

Specific BRCA1 and BRCA2 mutations are associated with some ethnic groups, such as those of Ashkenazi Jewish descent, and can be used to evaluate the risk of individuals in this group. Only about 0.2% of the U.S. population carries a BRCA1 or BRCA2 mutation. Because of this, genetic testing is not recommended for the general population.

PubMed GeneCards Summary for BRCA2 Gene: BRCA2 (breast cancer 2, early onset) is a protein-coding gene. Diseases associated with BRCA2 include fanconi anemia, complementation group d1, and breast-ovarian cancer, familial, 2. GO annotations related to this gene include histone acetyltransferase activity and single-stranded DNA binding. 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.

The contribution of BRCA1 and BRCA2 to inherited breast cancer was assessed by linkage and mutation analysis in 237 families, each with at least four cases of breast cancer, collected by the Breast Cancer Linkage Consortium. Families were included without regard to the occurrence of ovarian or other …

It spans over a length of 84.2 kb consisting of 27 exons. It consists of eight copies of BRC repeats and a ss DNA binding region. Like BRCA1 and RAD51 , BRCA2 relocates to replication sites following exposure of S phase cells to hydroxyurea or UV irradiation.

BRCA2 hereditary breast and ovarian cancer syndrome (BRCA2 HBOC) is an inherited condition that is characterized by an increased risk for a variety of different cancers. Women with this condition have a 49-55% risk of developing breast cancer, a 16-18% risk of developing ovarian cancer and a 62% risk of developing contralateral breast cancer by age 70.

BRCA2是一个磷蛋白，通常位于细胞核内[Bertwistle et al 1997。BRCA2蛋白没有可供识别的蛋白结构域，与1型乳腺癌敏感蛋白之间没有明显的关联。类似BRCA1，BRCA2在大部分组织和细胞类型中表达，这表明它不是乳腺癌和卵巢癌组织限定性的基因表达模式。
