| Gene Variant Descriptions | ALK F1245V lies within the protein kinase domain of the Alk protein (UniProt.org). F1245V confers a gain of function to the Alk protein, as it results in increased Alk kinase activity in vitro and leads to transformation activity in cell culture (PMID: 25517749, PMID: 33674381, PMID: 25517749). |

| ALK F1245V | neuroblastoma | predicted - sensitive | Entrectinib | Case Reports/Case Series | Actionable | In a combined analysis of 2 Phase I trials (ALKA-372-001, STARTRK-1), Rozlytrek (entrectinib) treatment resulted in a partial response that lasted 8.3 months in a patient with neuroblastoma harboring ALK F1245V, who remained on treatment for over 3.5 years due to clinical benefit (PMID: 28183697; NCT02097810). | 28183697 |
| ALK F1245V | neuroblastoma | predicted - sensitive | Lorlatinib | Case Reports/Case Series | Actionable | In a Phase I trial, Lorbrena (lorlatinib) treatment resulted in a complete response of marrow disease in a neuroblastoma patient harboring ALK F1245V, along with NF1 P2472fs and BRCA2 F2410fs (PMID: 37147298; NCT03107988). | 37147298 |
