For this aim, Ogata and his colleagues were pioneers when they suggested 4 cardinal parameters for a flow cytometric score for the diagnosis of MDS with little interexaminer variability.8 The 4 cardinal parameters are (1) the percentage of CD34+ myeloid progenitor cells, (2) the frequency of B‐cell precursors within the CD34+ compartment, (3) CD45 expression on myeloid progenitors relative to that on lymphocytes, and (4) the side‐scatter (SSC) properties of neutrophils in comparison with lymphocytes. This evidence concerns the gene CD34 and myelodysplastic syndrome.
