|ALK||L1152R||missense||unknown||ALK L1152R lies within the protein kinase domain of the Alk protein (UniProt.org). L1152R has been demonstrated to occur as a secondary drug resistance mutation in the context of ALK fusions (PMID: 21791641, PMID: 27091190), but has not been biochemically characterized and therefore, its effect on Alk protein function is unknown (PubMed, Apr 2020).||Y|

|ALK L1152R ALK rearrange||lung adenocarcinoma||predicted - resistant||Ceritinib||Case Reports/Case Series||Actionable||In a clinical case study, a patient with ALK-rearranged lung adenocarcinoma, which also harbored RB1 deletion and TP53 G154V and R158C mutations, demonstrated a partial response following treatment with Zykadia (ceritinib), however, progressed after 4 months and was found to have an acquired ALK L1152R mutation in a biopsy of a pleural nodule (PMID: 27091190).||27091190|
|ALK L1152R ALK rearrange||lung adenocarcinoma||predicted - sensitive||Alectinib||Case Reports/Case Series||Actionable||In a clinical case study, a patient with ALK-rearranged lung adenocarcinoma, which also harbored RB1 deletion and TP53 G154V and R158C mutations, was found to have an acquired ALK L1152R mutation in a biopsy of a pleural nodule following progression on Xalkori (crizotinib) and Zykadia (ceritinib), and was subsequently treated with Alecensa (alectinib), resulting in a partial response in all disease areas (PMID: 27091190).||27091190|
