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.
BReast CAncer gene 1 (BRCA1) and BReast CAncer gene 1 (BRCA2) are tumour suppressor genes with a central role in the homologous recombination repair (HRR) pathway. HRR is the major pathway for the repair of double-stranded DNA breaks.
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.
21 Ιουν 2022 · BRCA1 and BRCA2 are tumour suppressor genes that play a critical role in maintaining genomic stability via the DNA repair mechanism. DNA repair defects caused by BRCA1 and BRCA2 missense...
BRCA2 is the leading susceptibility gene for breast and ovarian cancer, with cumulative risks at age 80 years of up to 69% and 17%, respectively. Germline BRCA2 alterations can be found in around 2·5% of unselected patients with breast cancer and 6% of patients with ovarian cancer.
