The GG genotype of the rs3776455 SNP in the MTRR gene was associated with a significantly reduced risk to ALL (p = 1.21×10(-3); OR = 0.55), which resulted mainly from the reduced risk to B-cell and hyperdiploid-ALL.
We analysed common genetic polymorphisms of 5,10-methylenetetrahydrofolate reductase (MTHFR), thymidylate synthase (TS), methionine synthase (MS) and methionine synthase reductase (MTRR) in 68 children with ALL and 258 healthy controls to investigate their influence on the risk for ALL.
However, the results of stratified analyses revealed that MTRRA66G GG genotype was associated with decreased leukemia risk in the Caucasian population, in children and for acute lymphoblastic leukemia (ALL).
