There is one clinical trial.
We hypothesized that polymorphism MTHFR C677T and A1298C should be associated with HD-MTX-related toxicities in children with NHL. Therefore, we aimed to retrospectively explore their relationships in this analysis.
The most two extensively studied SNPs of MTHFR in relation to the toxicities of MTX are the C677T variant (Ala222Val, rs1801133) and A1298C variant (Glu 429Ala, rs1801131), both dampening the enzyme activity by 40-70%. --- C677T --- --- Ala222Val ---
Description: We recorded the toxicities that occurred to the patients after the MTX infusion, including hematological suppression, hepatotoxicity, nephrotoxicity, oral mucositis, vomiting and diarrhea.Measure: Observations of HD-MTX-related toxicities Time: 3 weeks
