| Impact List | missense |
| Protein Effect | loss of function |
| Gene Variant Descriptions | FANCA D1359Y does not lie within any known functional domains of the Fanca protein (UniProt.org). D1359Y confers a loss of function to the Fanca protein, as indicated by decreased Fancd2 and Fanci monoubiquitination, reduced Fancd2 foci formation upon MMC treatment in cultured cells (PMID: 28864460), decreased survival upon MMC treatment in FANCA-deficient cells, and decreased interaction with Fancc and Fancf in culture (PMID: 12444097). |

| FANCA inact mut | prostate cancer | sensitive | Enzalutamide + Talazoparib | Guideline | Actionable | Talzenna (talazoparib) plus Xtandi (enzalutamide) is included in guidelines as systemic therapy for patients with metastatic castration-resistant prostate cancer harboring a pathogenic germline or somatic FANCA mutation who have not been treated in the setting of castration-resistant prostate cancer (NCCN.org). | detail... |
| FANCA inact mut | prostate cancer | sensitive | Enzalutamide + Talazoparib | FDA approved | Actionable | In a Phase III trial (TALAPRO-2) that supported FDA approval, Talzenna (talazoparib) plus Xtandi (enzalutamide) improved median radiographic progression-free survival compared to enzalutamide plus placebo (27.9 vs 16.4 mo, HR 0.46, p=0.0003) in patients with metastatic castration-resistant prostate cancer harboring deficient homologous recombination repair genes including FANCA, with an HR of 0.66 (p=0.12) in patients with non-BRCA mutations treated with Talzenna (talazoparib) (PMID: 37285865; NCT03395197). | detail... 37285865 |
| FANCA inact mut | prostate cancer | predicted - sensitive | Abiraterone + Niraparib + Prednisone | Phase III | Actionable | In a Phase III trial (MAGNITUDE), Zejula (niraparib) in combination with Zytiga (abiraterone) and Adasone (prednisone) (AAP) improved radiographic progression-free survival (HR 0.59) compared to placebo and AAP in patients with metastatic castration-resistant prostate cancer harboring inactivating mutations in the homologous recombination repair (HRR)-Fanconi pathway genes including BRIP1, FANCA, and PALB2 (J Clin Oncol 40, no. 16_suppl (June 01, 2022) 5020; NCT03748641). | detail... |
| FANCA inact mut | prostate cancer | predicted - sensitive | Rucaparib | Case Reports/Case Series | Actionable | In a Phase II trial, 1 of 4 patients with metastatic castrate-resistant prostate cancer harboring deleterious FANCA alterations demonstrated a PSA response and complete radiographic response after treatment with Rubraca (rucaparib), which were ongoing at the time of visit cutoff (PMID: 32086346; NCT02952534). | 32086346 |
