Schematic representation of the chromosomal regions targeted by recurrent cytogenetic anomalies in CD4⁺, CD56⁺ DC2 acute leukemia.

Numbers correspond to patient UPN. Vertical solid black bars to the right of the chromosomes indicate the extent of deletion as determined by cytogenetics (R-banding and M-FISH) for each patient. Stars represent chromosomal breakpoints; open stars identify translocation breakpoints and filled stars identify inversion breakpoints. Stars combined with solid black bars indicate deletions resulting from unbalanced chromosomal rearrangements. Hatched lines delimit the minimal regions of deletion.
