Genomic instability in CLL patients exhibiting telomere dysfunction. Array-CGH (NimbleGen 720k whole genome array) from chromosomes 6-Y in 3 persons that display telomeric dysfunction in the form of telomeric LOH (#21 and #35) and fusion (#21 and #36). One person showed no evidence of telomere dysfunction. Binet stage, XpYp (mean ± SD), and lower 20th percentile are shown to the right of each rainbow CGH view.
