Testing for inherited changes in BRCA1 and BRCA2 can give several possible results: a positive result (a harmful change in the gene is present), a negative result (no harmful gene change is present), or a gene change (variant) of uncertain significance (VUS) result.

12 Αυγ 2016 · BRCA1 and BRCA2 are tumour-suppressor genes encoding proteins that are essential for the repair of DNA double-strand breaks by homologous recombination (HR). Cells that lack either BRCA1 or...
Abstract. The proteins encoded by the two major breast cancer susceptibility genes, BRCA1 and BRCA2, work in a common pathway of genome protection. However, the two proteins work at different stages in the DNA damage response (DDR) and in DNA repair.
9 Οκτ 2024 · BRCA1 functions in several crucial cellular pathways that preserve genome stability, including DNA-damage-induced cell-cycle checkpoint activation, DNA-damage repair, chromatin remodeling, transcriptional regulation, and apoptosis, and its mutation is linked to hereditary breast and ovarian cancer syndrome (HBOC). 32 According to the AACR ...
BRCA1 and BRCA2 are large genes in which multiple different types of pathogenic variant have been identified. The majority of these variants are individually rare, and several have only been reported in single families (so-called ‘private’ variants).
Evidence-based, expert-reviewed summary about the BRCA1 and BRCA2 genes and hereditary breast and ovarian cancer. This summary also contains information about the cancer risks associated with BRCA1/BRCA2, screening, risk-reduction, treatment, and prognosis.
23 Μαΐ 2024 · In this review, we examine the origin and resolution of ssDNA gaps and discuss the recent advances in understanding the role of BRCA1/2 in gap suppression. There are ample data showing that gap accumulation in BRCA1/2-deficient cells is linked to genomic instability and chemosensitivity.
