WT1 and chronic myelogenous leukemia, BCR-ABL1 positive: In bulk TCRβ sequenced patient samples (AML n = 21, chronic myeloid leukemia (CML) n = 26, and myelodysplastic syndrome n = 25), the median WT1-specific T-cell abundance was similar to healthy controls, but their VLD and RMF-specific TCR repertoires exhibited higher clonality with two patients presenting up to 13% of WT1-specific T-cells.
