This study aimed to evaluate the plasma homocysteine tHcy and folate levels as well as the methylenetetrahydrofolate reductase MTHFR C677T mutation in Egyptian subjects. Fasting total homocysteine tHcy and the MTHFR C677T mutation were evaluated in 50 healthy young control males age 35-50 years Gp1 50 elderly males age ranged between 50-75 years without any cardiovascular diseases Gp2 and 50 age matched elderly male patients Gp3 with myocardial infarction. There was a significant elevation of plasma tHcy in the patients group and Gp2 compared to the young control group Gp1 . The total plasma homocysteine tHcy in the control group Gp2 and the patients group were and pmol L respectively. The frequency of the TT genotype was 12 in the patient group compared with 8 in the young healthy controls and elderly subjects Gp2 . The CT genotype constituted 36 48 and 44 in the control group Gp2 and the patients group respectively. There was no significant difference in the occurrence of the TT genotype between the studied groups. Plasma tHcy correlated positively with age total cholesterol urea creatinine glucose levels and carotid intimal thickness CIT . Conclusion The MTHFR mutation does .
