WebApr 20, 2024 · Increased genomic instability upon defective DNA damage repair in BRCA1- and BRCA2-deficient cells is considered to be one of the driver events in tumorigenesis. However, the molecular pathogenic steps that drive this transformation in BRCA1 or BRCA2 mutation carriers are largely unknown. WebBRCA1 and BRCA2 are examples of genes that raise your cancer risk if they become altered. Having a variant BRCA gene greatly increases a woman's chance of developing breast cancer and ovarian cancer. They also increase a man's chance of developing male breast cancer and prostate cancer .

The concept of “BRCAness” was first described in 2004 to define the situation in which a homologous recombination repair (HRR) defect in a tumor relates to and phenocopies BRCA1 or BRCA2 loss-of-function mutations. Soon after the discovery of synthetic lethality of PARP1/2 inhibitors in BRCA1- or BRCA2-deficient cells, McCabe … WebJan 1, 1999 · Two predisposition genes, BRCA1 and BRCA2, have been mapped and cloned.
