BRCA1 (BReast CAncer gene 1) and BRCA2 (BReast CAncer gene 2) are genes that produce proteins that help repair damaged DNA. Everyone has two copies of each of these genes—one copy inherited from each parent.

The greatest risk factor for breast and ovarian cancer is inheritance of a mutation in one of the breast cancer susceptibility genes, BRCA1 or BRCA2. BRCA1 and BRCA2 are tumour suppressor genes, the coding regions of which show no homology to previously described proteins or to each other.
7 Νοε 2013 · The BC susceptibility gene, BRCA1, is located at chromosome 17q21 and codes for an 1863 amino acid protein involved in gene regulation processes following DNA damage. BRCA2 gene was mapped on chromosome 13q12.3 by positional cloning and translation following its transcription which leads to the formation of a protein with 3,418 amino acids.
BRCA1 and BRCA2 are genes involved in DNA repair. Constitutional (germline) pathogenic variants in these genes are associated with hereditary breast and ovarian cancer, as well as other cancers.
6 Αυγ 2024 · BRCA1 and BRCA2 gene mutations can occur at any location within the gene structure. It has been discovered that these genes possess a range of mutations that can increase susceptibility to BC and OC to different extents.
12 Αυγ 2016 · BRCA1 and BRCA2 are tumour-suppressor genes located on chromosomes 17q21 and 13q12, respectively. 1, 2, 3, 4 Functional BRCA proteins are involved in the maintenance of genome stability...
1 Σεπ 2004 · The discovery of the first gene associated with hereditary breast cancer, BRCA1, was anticipated to greatly increase our understanding of both hereditary and sporadic forms of breast cancer,...
