Clinical Report: Polymorphisms in DNA Repair Genes Linked to Leukemia
Overview
This review evaluates the association between DNA repair gene polymorphisms and leukemia risk, highlighting significant findings for specific genes. Notably, polymorphisms in XPD, XPC, and XRCC1 were linked to increased susceptibility to leukemia.
Background
Leukemia represents a significant global health concern, accounting for a notable percentage of cancer cases and deaths. Genetic factors, particularly polymorphisms in DNA repair genes, may play a crucial role in the development of leukemia, influencing individual susceptibility. Understanding these associations can aid in risk stratification and the development of targeted therapies.

Key Findings
ERCC1 8092C>A shows significant associations in homozygous and dominant models.
XPD Lys751Gln polymorphism is significantly associated with leukemia across all genetic models.
XPC Lys939Gln demonstrates significant associations in allelic, homozygous, and recessive models.
XRCC1 Arg194Trp and Arg399Gln polymorphisms are significantly associated with increased leukemia risk.
Gene expression analyses reveal subtype-specific alterations in DNA repair genes across leukemia datasets.
Clinical Implications
The identification of specific DNA repair gene polymorphisms associated with leukemia risk can inform genetic screening and risk assessment strategies. Clinicians may consider these genetic factors when evaluating patient susceptibility and tailoring treatment approaches.
Conclusion
This comprehensive review underscores the importance of DNA repair gene polymorphisms in leukemia susceptibility and highlights the need for further research to integrate these findings into clinical practice.
