PPM1D Mutations Drive Clonal Hematopoiesis in Response to Cytotoxic Chemotherapy
1 Nov 2018
Abstract excerpt
Clonal hematopoiesis (CH), in which stem cell clones dominate blood production, becomes increasingly common with age and can presage malignancy development. The conditions that promote ascendancy of particular clones are unclear. We found that mutations in PPM1D (protein phosphatase Mn 2+ /Mg 2+ -dependent 1D), a DNA damage response regulator that is frequently mutated in CH, were present in one-fifth of patients...
