Reports hematopoietic loss of the X chromosome in women as a genomic aging marker and examines its patterns and implications for female aging biology.
Key Takeaways
- Hematopoietic mosaic loss of the X chromosome (mLOX) increases with chronological age in women and shows measurable prevalence differences by age group.
- MLOX associates with altered blood cell counts and immune cell composition consistent with age‑related hematopoietic changes.
- The study links mLOX to higher incidence of selected age‑related clinical outcomes, indicating potential prognostic value.
