Clonal hematopoiesis and lymphoma-associated mutations in hematopoietic progenitors in B-cell non-Hodgkin lymphoma.

The contribution of clonal hematopoiesis (CH) and disease-initiating precursors in B-cell non-Hodgkin lymphomas (B-NHLs) remains underexplored. Such precursors may drive clonal evolution, contributing to disease progression and relapse. Here, we systematically profiled genetic precursor lesions in 43 patients with B-NHL using complementary whole-exome, targeted, and single-cell sequencing approaches. CH-associated mutations with a variant allele frequency of ≥1% were detected in the peripheral b...
