Gene Description | RAD51D, RAD51 paralog D, functions in homologous recombination in DNA repair and plays a role in telomere maintenance (PMID: 21821141, PMID: 23108668). Mutations in RAD51D are associated with increased susceptibility to ovarian cancer (PMID: 23372765, PMID: 21822267). | ||||||||||

RAD51D loss | Advanced Solid Tumor | sensitive | Olaparib | Preclinical | Actionable | In a preclinical study, cells harboring biallelic loss-of-function mutations in RAD51D had increased sensitivity to Lynparza (olaparib) compared to cells with wild-type RAD51D (PMID: 21822267). | 21822267 |
RAD51D inact mut | prostate cancer | sensitive | Olaparib | FDA approved - On Companion Diagnostic | Actionable | In a Phase III trial (PROfound) that supported FDA approval, Lynparza (olaparib) treatment significantly improved median imaging-based progression-free survival (5.8 vs 3.5 mo, HR 0.49, p<0.001) compared to control in patients with metastatic castration-resistant prostate cancer who progressed on hormone therapy and harbored deleterious or suspected deleterious mutations in homologous recombination repair genes, including RAD51D (PMID: 32343890; NCT02987543). | detail... detail... 32343890 |
