Abstract:
Objective To explore the distribution of methylenetetrahydrofolate reductase (MTHFR) C677T gene and MTHFR A1298C gene polymorphism among 1644 physical examinees in Taizhou region. Methods Fluorescence quantitative PCR method was used to detect MTHFR C677T and MTHFR A1298C genotype in 1644 physical examinees from Taizhou Central Hospital from September 2016 to September 2017. According to the characteristics of gender, the distribution features of MTHFR C677T and MTHFR A1298C genotype were described, and then were compared with data about the physical examinees in other cities in China. Results Among the 1644 physical examinees, MTHFR 677CC, 677CT and 677TT genotype frequency were 40.09％, 44.53％and 15.39％ respectively and MTHFR 677 allele frequency was 37.65％. MTHFR 1298AA, 1298AC and 1298CC genotype frequency were 65.69％, 30.47％ and 3.83％ respectively and MTHFR 1298 allele frequency was 19.07％. Statistical significance was found in genotype distribution of MTHFR C677T between males and females (P=0.036), and no statistical significance was found in genotype distribution of MTHFR A1298C between males and females (P=0.278) . As compared with the physical examinees in Henan, Wulumuqi and Beijing regions, there were statistically significance differences in the distribution of MTHFR C677T genotype and allele frequencies in Taizhou region (P <0.05) . Conclusion The distribution of MTHFR C677T gene polymorphism among physical examinees in Taizhou region is affected by gender, and the results shows certain regional specificity.
