As this population belongs to the mature compartment of erythropoiesis (CD117−/CD105−), we compared it both to the mature population of normal BM and to the mature, non‐aberrant compartment of the MDS cases, from which this population was excluded by using Boolean Logic (Mature AND NOT CD36−/dim/CD71−/dim). The gene discussed is TFRC; the disease is myelodysplastic syndrome.
