RUNX1 and myelodysplastic syndrome: A high CM blast count correlated with TP53 mutation (p=0.053, R=0.439) and group 2 (MDS with TP53 mutations and/or complex karyotype; p<0.001, R=0.561) whereas a high FC blast count correlated with RUNX1 mutation (p=0.024, R=0.266) and TP53 mutations (p=0.041, R=0.315).
