Gene ALK
Variant C1021V
Impact List missense
Protein Effect no effect - predicted
Gene Variant Descriptions ALK C1021V lies within the extracellular domain of the Alk protein (UniProt.org). C1021V does not result in Alk autophosphorylation and is not transforming in culture (PMID: 22086496), and therefore, is predicted to have no effect on Alk protein function.
Associated Drug Resistance
Category Variants Paths

ALK mutant ALK C1021V

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.

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
