DNA methylation levels at the HOXA5 locus. Squares represent gene location with light green=TSS-1500; Dark green=TSS-200; Red=Gene body; Magenta=1^st Exon; Dark blue=5’UTR; Cyan=3’UTR and diamonds represent sample values. A=Median methylation level of responders illustrated with orange diamonds (MNCs) and non-responders with blue diamonds (MNCs). B=Added CD34+ cells with red diamonds. C=All patients. D=Normal bone marrow with PMN illustrated with brown diamonds and CMP with green diamonds.
