Poor mobilization of autologous CD34+ peripheral blood stem cells in haematology patients undergoing autologous stem cell transplantation is associated with the presence of variants in genes implicated in clonal haematopoiesis of indeterminant potential.

Abstract excerpt

Clonal haematopoiesis of indeterminant potential (CHIP) increases in frequency with age. The effect of CHIP on the mobilization of autologous CD34+ peripheral blood stem cells (PBSC) has not been reported. This study uses a DNA-based targeted candidate gene approach to identify the presence of somatic mutations in ASXL1, DNMT3A, JAK2, SF3B1, TET2 and TP53 in CD34+ haematopoietic progenitor cell-apheresis products...
