Gene ALK
Variant F1245C
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions ALK F1245C lies within the protein kinase domain of the Alk protein (UniProt.org). Alk F1245C results in increased downstream signalling and is transforming in cell culture (PMID: 21838707).
Associated Drug Resistance

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

ALK F1245C neuroblastoma resistant Crizotinib Preclinical - Pdx & cell culture Actionable In a preclinical study, Xalkori (crizotinib) did not inhibit growth of neuroblastoma cells over expressing ALK F1245C in culture, and only delayed tumor growth in patient-derived xenograft models harboring ALK F1245C (PMID: 26554404). 26554404
ALK F1245C neuroblastoma sensitive Lorlatinib Preclinical - Pdx & cell culture Actionable In a preclinical study, Lorlatinib (PF-06463922) inhibited growth of neuroblastoma cells over expressing ALK F1245C in culture, and induced rapid and sustained complete tumor regression in patient-derived xenograft models harboring ALK F1245C (PMID: 26554404). 26554404
ALK F1245C Advanced Solid Tumor sensitive Lorlatinib Preclinical - Cell culture Actionable In a preclinical study, Lorlatinib (PF-06463922) inhibited foci formation more efficiently than Xalkori (crizotinib) in transformed cells over expressing ALK F1245C in culture (PMID: 26554404). 26554404
ALK F1245C Advanced Solid Tumor sensitive Brigatinib Preclinical - Cell culture Actionable In a preclinical study, a transformed cell line expressing ALK F1245C was sensitive to Alunbrig (brigatinib) in culture, resulting in cell growth inhibition (PMID: 27049722). 27049722
EML4 - ALK ALK F1245C lung non-small cell carcinoma sensitive Ceritinib Case Reports/Case Series Actionable In a clinical case study, a non-small cell lung cancer patient harboring EML4-ALK variant 3 that demonstrated resistance to treatment with Xalkori (crizotinib) after acquisition of ALK F1245C, achieved a complete radiographic response with no evidence of progression at 6 months following treatment with Zykadia (ceritinib) (PMID: 26775591). 26775591
EML4 - ALK ALK F1245C lung non-small cell carcinoma predicted - resistant Crizotinib Case Reports/Case Series Actionable In a clinical case study, a non-small cell lung cancer patient harboring EML4-ALK variant 3 demonstrated an initial response to treatment with Xalkori (crizotinib), but progressed after 27 months and was found to have acquired ALK F1245C (PMID: 26775591). 26775591

ALK mutant lung non-small cell carcinoma no benefit Crizotinib + Onalespib Phase II Actionable In a Phase II trial, Onalespib (AT13387) and Xalkori (crizotinib) combination treatment did not significantly improve median progression free survival (269 vs 266 days) or objective response rate (55.4%, 38/68 vs 45.3%, 31/68) compared to Xalkori (crizotinib) single treatment in patients with non-small cell lung carcinoma harboring either an ALK mutation or ALK rearrangement (J Clin Oncol 34, 2016 (suppl; abstr 9059); NCT01712217). detail...
