Fig. 1. Childhood leukemia subtypes and backtracking status.

Fig. 1

Top: ALL molecular subtype frequencies were modified from Pui et al. 2019. ALL subtypes that have been previously backtracked are highlighted in purple. Remaining B-cell ALL and T-cell ALL subtypes that have not been backtracked are colored blue, with T-cell subtypes highlighted by cross-hatching. Asterisks indicate that some T-cell ALL patients with KMT2A-rearranged (KMT2A-r) and other mutation events have been backtracked. Bottom: AML subtype frequencies from Huang et al. 2022, with previously backtracked subtypes highlighted in orange and remaining non-backtracked subtypes colored red.
