| Gene Variant Descriptions | ALK S1206R lies within the protein kinase domain of the Alk protein (UniProt.org). S1206R has been demonstrated to occur as a secondary drug resistance mutation in the context of EML4-ALK (PMID: 22034911), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, Oct 2025). |
