Homologous recombination deficiency in breast cancer: Implications for risk, cancer development, and therapy

Abstract excerpt

An underlying cause of breast cancers has been largely attributed to defects in the DNA damage response (DDR) pathway. In particular, the homologous recombination (HR) pathway repairs double-stranded breaks (DSBs) in DNA, ultimately protecting the cell from genomic instability and thus preventing the accumulation of transforming mutations. In line with this, mutations in a number of genes encoding HR proteins are...
