Toward More Complete Prognostication for Patients with Clonal Hematopoiesis

The study of clonal hematopoiesis is rapidly evolving, with the highest prevalence in aging populations and wide-ranging implications for health and disease, including an increased risk of subsequent myeloid malignancies and cardiovascular disease. In their article, Feusier and colleagues report on an expanded driver mutation list for capture of higher-risk clonal hematopoiesis mutations implicated in leukemia transformation. They also describe the prevalence of clonal hematopoiesis in several additional large studies, including, most importantly, in the pediatric context, which has not yet been extensively studied with respect to clonal hematopoiesis and clonal hematopoiesis-related sequelae.
