Analysis reveals that the DDX41 p.R525H mutation impairs proliferation in hematopoietic progenitors, suggesting a role in denderitic cell differentiation.
Key Points
DDX41 p.R525H mutation reduces proliferation of hematopoietic stem and progenitor cells while promoting differentiation into plasmacytoid dendritic cells.
Cells with p.R525H mutation formed fewer myeloid and erythroid colonies after DOX withdrawal, indicating impaired function.
Assessment used single-cell analysis and flow cytometry to explore the effects of the mutation on dendritic cells in induced pluripotent stem cell models.
Dysregulated dendritic cells may contribute to the pathogenesis of myeloid malignancies associated with DDX41 mutations.
