| Gene Variant Descriptions | ALK L1198V lies within the protein kinase domain of the Alk protein (UniProt.org). L1198V has been demonstrated to confer resistance to ALK inhibitors in the context of Alk fusions (PMID: 29636358, PMID: 35123209), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, Nov 2025). |
