SF3B1 and myelodysplastic syndrome: Here, we analysed their expression and showed that three of these miRNAs (miR‐581, miR‐1248 and miR‐1303) were downregulated in SF3B1‐mutated MDS patients and two of them (miR‐1248 and miR‐1303) showed also a moderate trend of correlation between miRNA and circRNA levels (Fig. 6A).
