Sex differences in DNMT3A-mutant clonal hematopoiesis and the effects of estrogen [scRNA-Seq]

Blood cancers are generally more common in males, and the prevalence of most mutations that drive clonal hematopoiesis and myeloid malignancies is higher in males. In contrast, hematopoietic DNMT3A mutations are more common in females. We sought to investigate if sex hormones might contribute to the female predominance of DNMT3A mutations. We used single-cell RNA- and ATAC-sequencing in murine models to examine genotype-specific sex differences and sex hormone effects on hematopoietic stem and progenitor cells.
