Background
ALK I1171T lies within the protein kinase domain of the Alk protein (UniProt.org). I1171T confers a gain of function on the Alk protein as indicated by ligand-independent autophosphorylation, activation of Erk1/2, and cell transformation (PMID: 29907598), and has been demonstrated to confer drug resistance in the context of ALK fusions in culture (PMID: 27009859). Patients harboring ALK I1171T mutations are resistant to crizotinib and alectinib, but sensitive to ceritinib and lorlatinib.
