In totality these efforts have identified a number of candidate predictive biomarkers of tumour cell response including ATM, ATR, CHEK1, CHEK2, DSS1, RAD51, NBS1, IPMK, NAMPT, ERCC1, the Fanconi anaemia complementation genes, PTEN and the TMPRSS2–ERG and EWSR1-FLI1 translocations (reviewed in [2]). Here, RAD51 is linked to neoplasm.
