A majority of MEC cases are associated with a specific chromosomal t(11;19)(q14-21;p12-13) translocation that joins exon 1 of the CRTC1 gene to exons 2–5 of the MAML2 gene, resulting in the expression of a new CRTC1-MAML2 fusion gene [4–7]. This evidence concerns the gene MAML2 and mucoepidermoid carcinoma.
