OBJECTIVE: To explore the method for clonal analysis of blood cells. METHODS: Thirty female AML patients and 20 normal female subjects were analysed by the analysis of X-linked HUMARA gene polymorphism and methylation pattern. RESULTS: The heterozygote rate of HUMARA gene in Chinese women was 88% and the gene had a stable methylation pattern. Out of 20 control females, 17 were heterozygotes and among them 15 were polyclonal, 2 (11.8%) showed skewed X-inactivation. All heterozygote AML were clonal hematopoiesis. CONCLUSION: HUMARA gene polymorphism is a good marker for clonality analysis of blood cells.
