NCIt definition : A fusion gene that results from a cryptic chromosomal rearrangement which fuses the
first 6 exons of the RUNX1 gene to exon 6 of the ZFPM2 gene. This rearrangement is
associated with one case of refractory anemia with excess blasts.;
NCIt note : Chan et al. (2005) described a t(X;21)(p22.3;q22.1) translocation in a patient with
myelodysplasia that fused the RUNX1 gene with the ZFPM2 gene. They anticipated that
the partner gene would be located on the X chromosome, but using FISH, they showed
that the ZFPM2 gene had been translocated from chromosome 8 to the X chromosome, indicating
that a complex chromosomal rearrangement had occurred in this patient.;
