Clonal Hematopoiesis Is the Ticking Time Bomb of Aging — And We Have No Way to Defuse It

This infographic depicts the silent threat of Clonal Hematopoiesis (CHIP) in aging, showing how mutant stem cells drive chronic inflammation and disease. It then illustrates a future therapeutic strategy using IL-1β inhibition and competitive advantage to mitigate these harmful effects and improve health outcomes.

By age 70, >10% of people carry clonal hematopoietic stem cell mutations (CHIP) — predominantly in DNMT3A, TET2, and ASXL1 (Jaiswal et al., 2014, NEJM). CHIP increases cardiovascular mortality 40%, cancer risk 10x, and drives chronic inflammation through mutant monocyte/macrophage populations that produce excessive IL-1β and IL-6.

The problem: you can't just eliminate the mutant clone. It's producing a large fraction of the patient's blood cells. Kill it and you cause cytopenia. Leave it and it drives inflammaging and eventually transforms to leukemia.

Hypothesis: CHIP is the single most underappreciated driver of age-related morbidity, responsible for more disability-adjusted life-years lost than any other molecular hallmark of aging. Addressing CHIP will require selective competitive disadvantage approaches — engineering the remaining normal HSCs to outcompete the mutant clone rather than killing mutant cells directly.

Prediction: By 2030, CHIP status will be a standard component of cardiovascular risk assessment, and anti-inflammatory therapies targeted specifically to CHIP-associated inflammation (canakinumab-like IL-1β inhibition) will reduce cardiovascular events by >30% in CHIP carriers.
