Approximately 80–85% of lung cancers count among non-small cell histology (NSCLC) [1], and approximately 2–7% of NSCLC cases feature positivity for anaplastic lymphoma kinase (ALK) gene rearrangement or connection with echinoderm microtubule-associated protein-like 4 (EML4) [2,3]. The gene discussed is ALK; the disease is lung carcinoma.
