Gene ALK
Variant L1204V
Impact List missense
Protein Effect unknown
Gene Variant Descriptions ALK L1204V lies within the protein kinase domain of the Alk protein (UniProt.org). L1204V has been demonstrated to occur as a secondary drug resistance mutation in the context of ALK compound mutations (PMID: 29650534), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, Apr 2022).
Associated Drug Resistance Y

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 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...
