Fusion genes namely BCR-ABL1, Paired box gene 3—Forkhead box protein O1 (PAX3-FOXO1), Fibroblast growth factor 3—Transforming acidic coiled-coil containing protein 3 (FGFR3-TACC3), Splicing factor proline and glutamine rich–Transcription factor binding to IGHM enhancer 3 (SFPQ-TFE3), Transmembrane protease, serine 2—ETS-related gene (TMPRSS2-ERG), Echinoderm microtubule-associated protein-like 4—Anaplastic lymphoma receptor tyrosine kinase (EML4-ALK) and MYB–Nuclear factor 1 B-type (MYB-NFIB) were shown to cause various types of cancer [27]. This evidence concerns the gene EML4 and cancer.
