Gene ALK
Variant A1251T
Impact List missense
Protein Effect loss of function - predicted
Gene Variant Descriptions ALK A1251T lies within the protein kinase domain of the Alk protein (UniProt.org). A1251T results in loss of kinase activity in an in vitro assay and is not transforming in cultured cells (PMID: 33674381), and therefore, is predicted to lead to a loss of Alk protein function.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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.

Molecular Profile Indication/Tumor Type Response Type Therapy Name Approval Status Evidence Type Efficacy Evidence References
ALK mutant lung non-small cell carcinoma no benefit Belizatinib Phase I Actionable In a Phase I trial, treatment with Belizatinib (TSR-011) in ALK inhibitor-naive non-small cell lung cancer patients (n=14) harboring either an ALK mutation, ALK amplification, or an ALK rearrangement resulted in a partial response in 6 patients and stable disease in 8 patients, however, it was determined that the drug resulted in limited efficacy and development of the drug was discontinued (PMID: 31217479; NCT02048488). 31217479
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...
