The reciprocal gene fusions AML1-FOG2 and FOG2-AML1 are both expressed.     ///    "AML1-FOG2, which fuses the DNA-binding domain of AML1 to most of FOG2, represses the transcriptional activity of both CBF and GATA1. "    ///    These results suggest a central role for CtBP in AML1-FOG2 transcriptional repression and implicate coordinated disruption of the AML1 and GATAdevelopmental programs in the pathogenesis of myelodysplasia..     ///    AML1-FOG2 retains a motif that recruits the corepressor C-terminal binding protein (CtBP) and these proteins associate in a protein complex.     ///    AML1-FOG2 fusion protein in myelodysplasia..
