Using a B-ALL gene expression classifier to identify Ph-like, ETV6-RUNX1⁺, and ERG-deleted/DUX4-rearranged cases. Bar chart of prediction probabilities for B-ALL samples grouped by molecular subtype BCR-ABL1, ETV6-RUNX1, ETV6 other, IL3-IGH, CRLF2-rearranged, ABL-class, JAK2-rearranged, or undefined. Samples were classified into Ph-like (red), ETV6-RUNX1⁺(orange), or ERG-deleted (blue) if they received a prediction score over 0.5 for any of these classes. Samples that were classified as other with a prediction score >0.75 or were not classified are gray. Bars are dark colored for samples where the patient either relapsed or died and light colored for all other cases.
