Clonal hematopoiesis: Molecular and clinical implications

Area of Science:

• Hematology
• Genetics
• Oncology

Background:

• Clonal hematopoiesis (CH) involves mutations in hematopoietic stem cells, expanding under selection.
• CH of indeterminate potential (CHIP) is defined by specific mutations (VAF ≥ 2%) without malignancy.
• CHIP is linked to aging, inflammation, smoking, and cancer history.

Purpose of the Study:

• To review recent advancements in CHIP.
• To discuss diagnostic and prognostic strategies for CHIP.
• To explore potential therapeutic approaches for CHIP.

Main Methods:

• Literature review of recent studies on CHIP.
• Analysis of diagnostic criteria and prognostic markers.
• Synthesis of current and future therapeutic strategies.

Main Results:

• CHIP is a premalignant condition with low but significant risk of hematologic malignancies.
• CHIP is associated with increased all-cause mortality, primarily from cardiovascular disease.
• Endothelial dysfunction is a key mechanism linking CHIP to cardiovascular complications.

Conclusions:

• CHIP represents a critical link between aging, genetic alterations, and adverse health outcomes.
• Accurate diagnosis and risk stratification are essential for managing CHIP patients.
• Further research into targeted therapies is crucial for mitigating CHIP-related risks.
