The C677T and A1298C polymorphisms in the 5,10-methylenetetrahydrofolate reductase gene (MTHFR) and the A66G polymorphism in the methionine sintase reductase gene (MTRR) were analyzed -using PCR-RFLP- in 141 individuals with Down syndrome and 200 control individuals (108 men and 92 women) in a Colombian coffee growing region. Allelic and genotypic frequencies were very similar in both populations. The 677CT, 1298AA and 66AG genotypes were most common in the Down syndrome population whereas the 677CC and 66AA genotypes were most common in the controls. In comparing allelic and genotypic frequencies in both populations using Pearson´s X2 test and Odds Ratio, no statistically significant differences were found. The MTHFR T---A haplotype was the most frequent...
