Aberrations in DNA repair genes occur in 20-30% of mCRPC tumours [1]. These aberrations are most frequently detected in genes involved in DNA damage repair through the homologous recombination repair (HRR) pathway. HRR genes include, but are not limited to, BRCA1, BRCA2, ATM, PALB2, FANCA, RAD51D, CHEK2, and CDK12 [2]. The presence of DNA repair deficiency may, amongst other factors, guide treatment selection in mCRPC [3]. Studies suggest that germline and somatic mutations in HRR genes may be predictive of the clinical benefit of poly(ADP-ribose) polymerase inhibitors (PARPi) [2].

This topic is limited to patients with mCRPC harbouring HRR gene mutations.
