|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 2020).|
