ABSTRACT
<p><b>OBJECTIVE</b>To assess whether polymorphisms of methylenetetrahydrofolate reductase (MTHFR) gene is associated with susceptibility to acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML) in Chinese Han children.</p><p><b>METHODS</b>The study has included 87 patients with ALL, 22 patients with AML and 120 healthy controls. All subjects were analyzed with reverse transcriptase-polymerase chain reaction-denaturing gradient gel electrophoresis and sequencing.</p><p><b>RESULTS</b>A 677CT genotype of the MTHFR gene was associated with decreased risk of ALL (OR=0.23, 95%CI 0.07-0.79). However, MTHFR A1298C genotypes were not associated with the risk of either disease. 677TT/1298AA and 677CC/1298AC genotypes were associated with increased risk of ALL(OR=3.78, 95% CI 1.38-10.40; OR=3.17, 95% CI 1.18-8.53, respectively), whereas the genotype 677CT/1298AA was associated with susceptibility to AML (OR=0.23, 95% CI 0.06-0.97).</p><p><b>CONCLUSION</b>Our data suggested that C677T polymorphism of MTHFR gene may increase the risk of childhood AML.</p>
