Gene ALK
Variant Q1188_L1190del
Impact List deletion
Protein Effect unknown
Gene Variant Descriptions ALK Q1188_L1190del results in the deletion of three amino acids in the protein kinase domain of the Alk protein from amino acids 1188 to 1190 (UniProt.org). Q1188_L1190del has been identified in the scientific literature (PMID: 33887694), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, May 2022).

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.

EML4 - ALK ALK Q1188_L1190del lung adenocarcinoma predicted - sensitive Lorlatinib Case Reports/Case Series Actionable In a clinical case study, Lorbrena (lorlatinib) treatment resulted in significant metabolic response and stable disease lasting 11 months in an EML4-ALK-positive lung adenocarcinoma patient harboring ALK Q1188_L1190del who had previously progressed on Xalkori (crizotinib) and Zykadia (ceritinib) treatment (PMID: 33887694). 33887694

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...
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
