[Clonal haematopoiesis: A concise review].

Area of Science:

• Hematology
• Genetics
• Oncology

Background:

• Clonal hematopoiesis of undetermined significance (CHIP) is characterized by somatic mutations in hematopoietic cells.
• These mutations often occur in genes like DNMT3A, TET2, and ASXL1, previously linked to myeloid malignancies.
• CHIP is identified in individuals without overt hematologic diseases.

Purpose of the Study:

• To define Clonal Hematopoiesis of Undetermined Significance (CHIP).
• To outline the genetic basis and associated risks of CHIP.
• To explore the potential clinical utility of CHIP detection.

Main Methods:

• Utilizing high-throughput gene sequencing, specifically Next-Generation Sequencing (NGS).
• Identifying somatic mutations in hematopoietic cells.
• Analyzing mutations in genes commonly affected in acute myeloid leukemia and myelodysplastic syndrome.

Main Results:

• CHIP is associated with an elevated annual risk (0.5–1%) of developing myeloid or lymphoid malignancies.
• CHIP is linked to increased risks of overall mortality and cardiovascular diseases.
• Current CHIP detection is primarily in basic science research.

Conclusions:

• CHIP represents a significant risk factor for hematologic malignancies and other serious health conditions.
• Next-Generation Sequencing (NGS) is the key technology for CHIP identification.
• Emerging evidence suggests CHIP detection holds considerable clinical interest for risk stratification and management.
