Analysing the Pellagatti et al. dataset (GSE19429), a total of 5 840 genes showed significant differences (FDR ≤ 0.05) in mRNA expression levels between CD34+ cell from RARS patients (using only MDS-RS samples with normal karyotype) and their control group: 3 697 and 2 143 genes were over and under-expressed, respectively, in the RARS samples. Here, CD34 is linked to myelodysplastic syndrome with ring sideroblasts.
