Analysis of clonal heterogeneity in matched DX‐REL samples showed a trend towards reduced entropy levels in REL samples ( P = 0.064), with six of 10 patients showing lower entropy levels in the REL samples (Fig. 6D ), supporting previous data on DX samples of high levels of clonal heterogeneity as a favorable prognostic factor in HHD‐B‐ALL.
