However, unlike fusion transcripts that occur in other salivary gland tumors, which result in the production of fusion proteins like the MYB-NFIB fusion genes produced in adenoid cystic carcinoma [19,21], in this case the result is a more highly transcribed NR4A3 or NR4A2 gene, but no fusion proteins. Here, NFIB is linked to adenoid cystic carcinoma.
