DNMT3A and myelodysplastic syndrome: In the studies of more than 100 genes by high-throughput DNA sequencing, Haferlach et al. [43] and Papaemmanuil et al. [44] also found a positive correlation between DNMT3A and SF3B1 mutations, indicating that interaction between these two gene mutations may play a role in the pathogenesis of MDS, but further investigations are needed to elucidate its mechanism, especially in RARS subtype.
