However, with the fusion gene that joints the echinoderm microtubule-associated protein-like 4 (EML4) gene with ALK gene was found in a subset of NSCLC in 2007 [5] and other fusion genes with ALK have been reported in NSCLC Subsequently [6, 7], ALK translocation has been considered to be a potential oncogenic driver and an important therapeutic target in NSCLC. Here, EML4 is linked to non-small cell lung carcinoma.
