Abstract:
In this study, 108 pediatric patients with bone marrow (BM) failure and leukemia predisposition were evaluated for presence of clonal hematopoiesis in peripheral blood (PB) and BM. Robust PB-BM concordance for mutations but decreased sensitivity in PB for chromosomal abnormalities was found.
