| Gene Variant Descriptions | ABL1 K357dup indicates the insertion of the duplicate amino acid, lysine (K)-357, in the protein kinase domain of the Abl1 protein (UniProt.org). K357dup has been demonstrated to occur as a secondary resistance mutation in the context of BCR-ABL1 (PMID: 22387050), but has not been biochemically characterized and therefore, its effect on Abl1 protein function is unknown (PubMed, Mar 2026). |
