We analyzed 12 DDX41-m (cases M5-M6, M8-M11, M15-M20) on which suitable BM sample could be obtained our investigations, 10 normal controls and 10 MDS samples and predominantly focused our analysis on CD34+ progenitor cells and nucleated red blood cells often showing aberrant immunophenotypes in MDS (Figures 5, 6). This evidence concerns the gene CD34 and myelodysplastic syndrome.
