Fig. 4. Distinct genetic subclones form an overlapping immunophenotypic continuum in a case of pediatric AML.

a Three timepoints sampled with DAb-seq during treatment comprise a mixture of independent clones (KRAS G13D heterozygous blasts, yellow; FLT3 D835Y blasts, red). The wild-type compartment contains additional cells with a blast-like immunophenotype lacking detectable mutations. b Heatmap of log-transformed corrected antibody counts and genotyping calls for the KRAS and FLT3 loci for each cell across all timepoints. The heatmap is grouped by genotype. Cells with wild-type genotype but blast-like immunophenotype are labeled separately. c UMAP embedding of all cells from all timepoints based on log-transformed corrected antibody counts. Color indicates mutation status as in a. The blast compartment is overlaid with a spline approximating the gradient of the second principal component of the antibody count matrix (shown in inlet figure) and indicates a gradual change in immunophenotype. d Moving average expression of antibodies and fraction of mutated cells sorted by the second principal component of the antibody count matrix. The overlapping phenotypic continuum between the genetically distinct blast clones is apparent. Source data are provided as a Source data file.
