Detection of KRASG12Dmutation and inv(16) in sorted blasts and eosinophils. (A) Dot plot of bone marrow cells (yellow: eosinophils; red: blasts; blue: lymphocytes; pink: monocytes; green: neutrophils). (B) Sorted blasts (CD45dimCD34+CD15−CD117+SSClo). (C) Sorted eosinophils (CD45+CD34−CD117−CD15+SSChi). FISH studies using CBFB break-apart probes (Abbott Molecular, Des Plaines, IL) showing a split signal pattern of CBFB probes (ie, inv(16)), in (D) sorted blasts and in (E) eosinophils. Detection of KRASG12D in (F) sorted blasts, (G) eosinophils, and (H) FFPE adrenal tissue by ddPCR. Blue dots represent mutant droplets; green dots represent wild-type droplets, and red or gray dots represent empty droplets. SSC-H, side-scatter height.
