In summary, this meta-analysis suggests that MTHFR A1298C polymorphism is associated with increased cervical cancer and lymphoma risk in Asians, and MTHFR A1298C polymorphism is associated with decreased colorectal cancer risk in Asians.
Although the MTHFR A1298C polymorphism was not associated with OS in CRC, this polymorphism was associated with significantly shorter OS in rectal cancer.
In this hospital-based case-control study, the role of MTHFR C677T (rs1801133) and A1298C (rs1801131) genotypes in determining CRC risk were investigated among 362 patients with CRC and an equal number of age- and gender-matched healthy individuals.
Relevance of methylenetetrahydrofolate reductase gene variants C677T and A1298C with response to fluoropyrimidine-based chemotherapy in colorectal cancer: a systematic review and meta-analysis.
The present study focused on understanding the prognostic value of the methylenetetrahydrofolate reductase (MTHFR) single nucleotide polymorphisms rs1801133 (C667T) and rs1801131 (A1298C) in patients with colorectal cancer (CRC).
