A common mutation in BRCA2 that predisposes to a variety of cancers is found in both Jewish Ashkenazi and non-Jewish individuals. Berman DB, Costalas J, Schultz DC, Grana G, Daly M, Godwin AK. Cancer Res. 1996 Aug 1;56 (15):3409-14. PMID 8758903

Both BRCA1 and BRCA2 are tumor suppressor genes that usually have the job of controlling cell growth and cell death. Everyone has two BRCA1 (one on each chromosome #17) and two BRCA2 genes (one on each chromosome #13).

The BRCA2 gene is larger than BRCA1, and it has a 10.3 kb open reading frame encoding a 384 kDa nuclear protein (Figure 1). BRCA2 does not share a high degree of sequence homology with other known genes, and the generated protein is comprised of regions with domains that are undefined [12].

A team from Institut Curie, in collaboration with a group of CEA, revealed an additional role of BRCA2 in the alignment of chromosomes during mitosis (cell division)

The BRCA2 gene is located on the long (q) arm of chromosome 13 at position 12.3 (13q12.3). The human reference BRCA 2 gene contains 27 exons, and the cDNA has 10,254 base pairs [17] coding for a protein of 3418 amino acids. The complete BRCA2 gene and mutations in chromosome 13q-linked kindreds.

Breast carcinoma is the most common malignancy among women in developed countries. Because family history remains the strongest single predictor of breast cancer risk, attention has focused on the role of highly penetrant, dominantly inherited genes in cancer-prone kindreds (1). This report is the first to describe the highly pathogenic variant in the BRCA2 gene (rs483353122) and the likely damaging germline variant in the MUTYH gene (rs35352891) in Russian Mongoloid BC patients with young-onset and/or bilateral and/or familial BC. BRCA2 is located on chromosome 13. Mutations in this gene are also transmitted in an autosomal dominant pattern in a family. Both BRCA1 and BRCA2 are tumor suppressor genes that usually have the job of controlling cell growth and cell death.

CAS Google Scholar Se hela listan på academic.oup.com The breast cancer susceptibility gene, BRCA2, was recently localized to chromosome 13q12-q13. Here we report the identification of a gene in which we have detected six different germline mutations in breast cancer families that are likely to be due to BRCA2. The genes most commonly affected in hereditary breast and ovarian cancer are the breast cancer 1 (BRCA1) and breast cancer 2 (BRCA2) genes. About 3% of breast cancers (about 6,000 women per year) and 10% of ovarian cancers (about 2,000 women per year) result from inherited mutations in the BRCA1 and BRCA2 genes.

The BRCA2 gene was found on chromosome 13q12.3 in human. The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele.
