In summary, we found that the MTHFR C677T polymorphism is associated with a significant increased risk in congenital heart disease in the fetal population.
A meta-analysis of polymorphism C677T (rs1801133) of the methylene tetrahydrofolate reductase (MTHFR) gene as a potential risk factor for congenital heart disease (CHD) in Chinese paediatric population was studied in view of the previously reported controversial results.
Association between C677T polymorphism of methylene tetrahydrofolate reductase and congenital heart disease: meta-analysis of 7697 cases and 13,125 controls.
The aim of this study was to evaluate whether the cytosine-to-thymine mutation at base 677 of the methylenetetrahydrofolate reductase gene (MTHFR C677T), which has been associated with neural tube defects and congenital oral cleft, is also associated with tetralogy of Fallot (TF), a congenital heart disease.
