MCM7 polymorphisms associated with the AML relapse and overall survival

Area of Science:

• Genetics
• Oncology
• Molecular Biology

Background:

• The minichromosome maintenance complex component 7 (MCM7) gene is crucial for DNA replication initiation and is implicated in cancer development.
• MCM7 gene polymorphisms have been investigated as potential contributors to various cancer risks.

Purpose of the Study:

• To investigate the association between seven MCM7 gene polymorphisms and the risk of acute myeloid leukemia (AML).
• To explore the relationship between MCM7 polymorphisms and the prognosis of AML, including relapse and overall survival.

Main Methods:

• Genotyping of seven MCM7 polymorphisms in 103 AML patients and 241 healthy controls.
• Statistical analysis to assess associations between MCM7 genotypes/haplotypes and AML risk, relapse, and survival.

Main Results:

• No significant association was found between MCM7 polymorphisms and the overall risk of AML.
• Specific MCM7 polymorphisms (rs2070215, rs1534309) and haplotypes (ht1, ht2) were significantly associated with AML relapse and overall survival.
• The rs2070215 polymorphism demonstrated a protective effect against AML relapse, while the CC genotype of rs1534309 was linked to higher overall survival rates.

Conclusions:

• MCM7 gene polymorphisms do not appear to influence the risk of developing AML.
• MCM7 polymorphisms may serve as valuable biomarkers for predicting the prognosis, including relapse risk and survival outcomes, in AML patients.
