| Gene Variant Descriptions | ALK D1225N lies within the protein kinase domain of the Alk protein (UniProt.org). D1225N has been identified in the scientific literature (PMID: 37529699), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, Sep 2025). |
