| Gene | RAD54L |
| Variant | Q90* |
| Impact List | nonsense |
| Protein Effect | loss of function - predicted |
| Gene Variant Descriptions | RAD54L Q90* results in a premature truncation of the Rad54l protein at amino acid 90 of 747 (UniProt.org). Due to the loss of the ATP-binding and C-terminal helicase domains (UniProt.org), Q90* is predicted to lead to a loss of Rad54l protein function. |

| RAD54L inact mut | prostate cancer | sensitive | Olaparib | FDA approved - On Companion Diagnostic | Actionable | In a Phase III trial (PROfound) that supported FDA approval, Lynparza (olaparib) improved median imaging-based progression-free survival (5.8 vs 3.5 mo, HR 0.49, p<0.001) compared to control in metastatic castration-resistant prostate cancer patients harboring deleterious or suspected deleterious mutations in homologous recombination repair genes who progressed on hormone therapy, HR for progression or death was 0.33 in RAD54L-mutant patients (PMID: 32343890; NCT02987543). | detail... detail... 32343890 |
