| Gene Variant Descriptions | ALK D1276_R1279delinsE results in a deletion of four amino acids in the protein kinase domain of the Alk protein from amino acids 1276 to 1279, combined with the insertion of a glutamic acid (E) at the same site (UniProt.org). D1276_R1279delinsE results in constitutive activation of Alk and is transforming in cell culture (PMID: 37147298). |
