Study on the polymorphysm of MTHFR gene in coronary heart disease in Guizhou / 中国实用内科杂志

ABSTRACT

Objective Study on methylenetetrahydrofolate reductase(MTHFR)gene polymorphism in coronary heart disease.Methods Detect the MTHFR C677T gene polymorphism by PCR-RFLP in 73 cases of healthy individuals and 87 cases of coronary heart diseas(CHD).Results At the site of 677,the T allele frequencies are 18.5%,36.1%,respectively,for healthy individuals and 87 cases of coronary heart disease.The frequecies of MTHFR CT genotype and T allel were significantly higher in disease groups.There are significant differences between disease group and control group(P
