With regard to distinct subgroups compared to healthy BM, patients with 3p CDR within CN-AML (p = 0.007), 3p CDR within CK-AML (p < 0.0001) as well as CN-AML (p = 0.0005) and CK-AML (p < 0.0001) displayed significantly lower PPP4R2 mRNA levels (Figure 1C). This evidence concerns the gene PPP4R2 and acute myeloid leukemia.
