ABSTRACT
<p><b>OBJECTIVE</b>To investigate the association of polymorphisms in the apolipoprotein B gene (APOB) 3'variable number of tandem repeat with natural longevity in the Xinjiang Uighur nationality people.</p><p><b>METHODS</b>Totally 191 healthy individuals over 90 years and 53 individuals aged 65-70 years were recruited among Xinjiang Uighur population, the nationality, gender and living area were matched. Genotyping was performed using polymerase chain reaction-sequence specific primer(PCR-SSP) and PCR-sequencing.</p><p><b>RESULTS</b>Fourteen alleles were found in the Xinjiang Uighur nationality population. The frequency of HVE36 and HVE42 in the natural longevity group were significantly higher than that in the control group (both P<0.05) and HVE44, HVE46, HVE48 and HVE58 were only found in the natural longevity group. However, the frequency of HVE26, HVE30 and HVE34 were markedly lower in the natural longevity group compared to the control group. Logistic regression analyses revealed that allele L and the genotypes LL were positively associated with age, whereas the allele S and genotype SS were negatively associated with age (both P<0.05). Each allele consists of 15 bp tandem repeats with rich-AT by PCR-sequencing.</p><p><b>CONCLUSION</b>These results indicate that the S allele, and SS genotype are frail factors in China Uighur natural longevity people, whereas allele L and genotypes LL are protective factors.</p>
