Other reported genetic abnormalities include supernumerary ring chromosomes and a derivative chromosome 13 segment, (13) translocation t(2; 6)(q31; p21.
Interestingly, fluorescence in situ hybridization (FISH) with an MLL break-apart probe set, performed on both interphase nuclei and metaphase spreads, confirmed the presence of 3 extra copies of the MLL gene on the derivative chromosome 11.
The 5' EWSR1 end of the probe remains on the derivative chromosome 22, whereas the 3' EWSR1 end of the probe moves to the derivative chromosome 12.
