In the adult subgroup, there was no significant association between the C677T variant and ALL risk (Dominant model: OR(RE)=0.88, 95% CI: 0.45-1.72, p=0.72).

Genotyping of MTHFR polymorphism, C677T particularly, prior to treatment for ALL is likely to be useful with the aim of tailoring MTX therapy and thus reducing the MTX-related toxicities.
