Methods Apolipoprotein E genotypes were determined in 164 unrelated Uygurs including 35 persons aged 90 years or older, 71 men aged 20-35 and 54 men with myocardial infarction by using polymerase chain reaction-restriction fragment length polymorphism. Apolipoprotein E gene polymorphism was analyzed among three groups. Results There was statistically significant difference in the ε4 allele frequencies among three groups. The ε4 allele frequency in olds was the lowest (0.057), while in patients suffering from myocardial infarction (MI) was the highest (0.213). In MI patients the average age of first attack in ε4 allele carriers was significantly younger than that of non-carries, 51.3 and 58.3 years, respectively (P<0.05). Conclusion ApoE genotype may have some impact on human longevity.展开更多
