While TP53 predominated in our cohort, only one patient was detected with a TP53 variant in the MDS/MPN and MPN sub‐group, where RUNX1 (n = 6, 43%) and the RASopathies‐related genes, CBL (n = 5, 36%) and NF1 (n = 1, 7%) were most prevalent (Figure 2, Table 2). This evidence concerns the gene NF1 and myelodysplastic syndrome.
