| Gene Variant Descriptions | ALK G1123S lies within the protein kinase domain of the Alk protein (UniProt.org). G1123S has been demonstrated to confer drug resistance in culture (PMID: 26134233, PMID: 21948233), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, Nov 2025). |
