Abstract

Objectives

To investigate the relationship of the MTHFR polymorphisms (C677T) and the risk of CRC by meta-analysis.

Methods

Relevant literatures concerning the association between the MTHFR C677T polymorphism and the risk of CRC were searched using the electronic database PubMed, EMBASE, Cochrane and China National Knowledge Infrastructure (CNKI). Odds ratio (ORs) and 95 % confidence intervals (CIs) were determined to assess the gene–disease association using fixed or random effect models, according to the heterogeneity among included studies.

Results

The study shows that the MTHFR 677 TT homozygous genotype significantly decreases the risk of CRC in Asians (TT vs. CC: OR = 0.82, 95 % CI 0.73–0.92; TT vs. CT: OR = 0.84, 95 % CI 0.75–0.94; TT vs. CC+TT: OR = 0.83, 95 % CI 0.75–0.93).

Conclusion

This meta-analysis indicated that the MTHFR 677 TT homozygous genotype decreased the risk of CRC in Asians, while the MTHFR 677 CT heterozygous genotype did not contribute to CRC susceptibility.
