Clonal Hematopoiesis is Associated with Inherited Variants

Loh et al. found 52 inherited, rare, large-effect coding or splice variants in 7 genes that were associated with greatly increased vulnerability to clonal hematopoiesis. Clonally expanded blood cells that contain somatic mutations (clonal hematopoiesis) are commonly acquired with age and increase the risk of blood cancer. These inherited variants led to specific, acquired mutations that set the stage for cancer. This work was published by Nature and covered by HMS news and the Broad Institute.
