Abstract

Somatic variants accumulate in all organs with age, with a positive selection of clonal populations that provide a fitness advantage during times of heightened cellular stress leading to clonal expansion. Easily measured within the hematopoietic compartment, clonal hematopoiesis (CH) is now recognized as a common process in which hematopoietic clones with somatic variants associated with hematopoietic neoplasms exist within the blood or bone marrow of individuals without evidence of malignancy. Most cases of CH involve a limited number of genes, most commonly DNMT3A, TET2, and ASXL1. CH confers risk for solid and hematopoietic malignancies as well as cardiovascular and numerous inflammatory diseases and offers opportunities for cancer prevention. Here, we explore the genetic and environmental factors that predispose individuals to CH with unique variant signatures and discuss how CH drives cancer progression with the goals of improving individual cancer risk stratification, identifying key intervention opportunities, and understanding how CH impacts therapeutic strategies and outcomes.

期刊介绍： Since its establishment in 1896, the Journal of Experimental Medicine (JEM) has steadfastly pursued the publication of enduring and exceptional studies in medical biology. In an era where numerous publishing groups are introducing specialized journals, we recognize the importance of offering a distinguished platform for studies that seamlessly integrate various disciplines within the pathogenesis field. Our unique editorial system, driven by a commitment to exceptional author service, involves two collaborative groups of editors: professional editors with robust scientific backgrounds and full-time practicing scientists. Each paper undergoes evaluation by at least one editor from both groups before external review. Weekly editorial meetings facilitate comprehensive discussions on papers, incorporating external referee comments, and ensure swift decisions without unnecessary demands for extensive revisions. Encompassing human studies and diverse in vivo experimental models of human disease, our focus within medical biology spans genetics, inflammation, immunity, infectious disease, cancer, vascular biology, metabolic disorders, neuroscience, and stem cell biology. We eagerly welcome reports ranging from atomic-level analyses to clinical interventions that unveil new mechanistic insights.
