A chromosomal aberration involving MRTFB is found in 3 chondroid lipomas. Translocation t(11;16)(q13;p13) with MRTFB produces a ZFTA-MRTFB fusion protein (PubMed:20607705). A chromosomal aberration involving RELA is found in more than two-thirds of supratentorial ependymomas. Translocation with RELA produces a ZFTA-RELA fusion protein. ZFTA-RELA translocations are potent oncogenes that probably transform neural stem cells by driving an aberrant NF-kappa-B transcription program (PubMed:24553141). Probable cloning artifact.
