In an effort to identify novel genetic dependencies of lung cancer, we searched the CCLE (Cancer Cell Line Encyclopedia) database for NSCLC cell lines that harbored mutations in ABL1 or ABL2 (Barretina et al, 2012) and identified four lung adenocarcinoma cell lines H1915 (ABL1‐R351W), H2110 (ABL1‐G340L), H650 (ABL2‐W469C), and H1623 (ABL2‐Y399C). This evidence concerns the gene ABL2 and lung adenocarcinoma.
