The Mnt gene encodes a Mad-family bHLH transcription factor located on human 17p13.3. Mnt is one of 20 genes deleted in a heterozygous fashion in Miller-Dieker syndrome (MDS), a contiguous gene syndrome that consists of severe neuronal migration defects and craniofacial dysmorphic features. Mnt can inhibit Myc-dependent cell transformation and is hypothesized to counterbalance the effects of c-Myc on growth and proliferation in vivo by competing with Myc for binding to Max and by repressing target genes activated by Myc : Max heterodimers. Unlike the related Mad family members, Mnt is expressed ubiquitously and Mnt/Max heterodimers are found in proliferating cells that contain Myc/Max heterodimers, suggesting a unique role for Mnt during proliferation. To examine the role of Mnt in vivo, we produced mice with null (Mnt(KO)) and loxP-flanked conditional knock-out (Mnt(CKO)) alleles of Mnt. Virtually all Mnt(KO/KO) mutants in a mixed (129S6 x NIH Black Swiss) or inbred (129S6) genetic background died perinatally. Mnt-deficient embryos exhibited small size throughout development and showed reduced levels of c-Myc and N-Myc. In addition, 37% of the mixed background mutants displayed cleft palate as well as retardation of skull development, a phenotype not observed in the inbred mutants. These results demonstrate an important role for Mnt in embryonic development and survival, and suggest that Mnt may play a role in the craniofacial defects displayed by MDS patients.
