This study tested the hypothesis that maternal folic acid supplementation before or during pregnancy reduces AL risk, accounting for the SNPs rs1801133 (C677T) and rs1801131 (A1298C) in MTHFR and rs1801394 (A66G) and rs1532268 (C524T) in MTRR, assumed to modify folate metabolism.
We retrospectively analyzed the incidence of MTHFR C677T and the influence of genotype on methotrexate (MTX) toxicity in patients with acute leukemia undergoing maintenance chemotherapy.
