IDH1 and acute myeloid leukemia: In order to determine clinical relevance of upregulated PDGFRA expression, we compared overall survival of patients with IDH1-mut AML with high (above median) or low (below median) PDGFRA expression (n = 8 versus n = 8) as well as IDH1-wt patient with high or low PDGFRA (n = 68 versus n = 68) using published clinical data by Bamopoulos et al. [16].
