Gene Summary
This gene encodes a protein with three HTH DNA-binding domains that functions as a transcription regulator. This protein plays an essential role in the regulation of hematopoiesis. This gene may be aberrently expressed or rearranged or undergo translocation in leukemias and lymphomas, and is considered to be an oncogene. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Adenoid cystic carcinoma (ACC) is a common salivary gland malignancy. The malignancy is associated with gene fusions between MYB, MYBL1, and NFIB. FISH analysis was used to evaluate any rearrangements in these genes with the use of our break apart probes. It was found through FISH that MYB aberrations were preserved between primary tumors and metastases. Additionally, MYB and NFIB aberrations are preserved in ACC metastatic lesions.
HPV-related multiphenotypic sinonasal carcinoma (HMSC) is a sinonasal tract neoplasm with a salivary gland tumor-like appearance. The morphologic profile of HMSC is still not fully understood and is under study. One aspect of this morphologic study included FISH analysis with our MYB break apart probes. No rearrangements in MYB were detected by FISH in the cases under study. It was concluded that MYB protein cannot be used to separate adenoid cystic carcinoma from HMSC.
Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC) is a tumor of the sinonasal tract with a wide morphologic spectrum. A case study of HMSC was under analysis to contribute more information about it to the literature. In addition to other analyses, FISH was done with our MYB break apart probe. It was concluded that HMSC tumors can have a long-term recurrence as well as indolent behavior.
Adenomyoepithelioma (AME) and adenoid cystic carcinoma (ACC) often occur simultaneously, suggesting that AME may be a related or precursor lesion to ACC. MYB gene rearrangements are frequently reported with ACC. Therefore, the rates of MYB rearrangement were compared between AME and ACC. Translocation of the MYB gene was detected by using FISH analysis with our MYB break apart probe. It was concluded that AMEs do not have MYB gene rearrangement.
