Summary of aCNA, cnLOH, gene mutations, and karyotype changes in 28 paired AML samples procured at presentation and relapse. Blue fields indicate presence of aCNA or cnLOH or abnormal karyotypes. Yellow fields indicate presence of gene mutations. Green fields indicate a change in the status of a gene mutation. *MI-AML-15 had no germ line DNA available; for this case only CNV > 1 Mb are included in this analysis. **MI-AML-137 shows a different FLT3 ITD between enrollment and relapse. ***The relapse specimen of MI-AML-044 demonstrated elongation of a segment of CN-LOH present in the enrollment specimen.
