A new type of MAML2 fusion in mucoepidermoid carcinoma.

Author information

Center for Human Genetics, University of Bremen, Bremen, Germany.


The present study reports for the first time a CRTC3-MAML2 fusion gene in a mucoepidermoid carcinoma, as determined by RT-PCR and sequencing. We screened a total of 67 formalin-fixed, paraffin-embedded mucoepidermoid carcinomas for the presence of chimeric genes. In one of these samples, a CRTC3-MAML2 fusion gene was detected. Thus, this report demonstrates the existence of a fusion of MAML2 with CREB regulated transcriptional coactivator CRTC3 additional to the already known fusion of MAML2 and CRTC1. Both gene fusions seem to result in an identical tumor phenotype and the fusion genes CRTC1-MAML2 and CRTC3-MAML2 may play a similar role in the development of mucoepidermoid carcinomas.
