Apolipoprotein E gene polymorphism in men with coronary atherosclerosis in Siberia.

Polymorphism of coding fragment of APOE gene was analyzed in two groups of men. The main group consisted of 77 residents of the West Siberian region aged 45-65 years with coronary atherosclerosis (documented by coronary angiography) without acute coronary syndrome with stable effort angina, functional class II-IV. The reference group consisted of 350 residents of Novosibirsk, aged 45-69 years. Statistically significant associations between genotypes of APOE gene coding part polymorphism and some key lipid risk factors (blood total and LDL cholesterol, atherogenic index, etc.) for coronary atherosclerosis were found in male residents of the West Siberian region. Elevated total mean level of cholesterol was detected in male residents of Novosibirsk with the APOE genotypes containing ε4 allele.
