چکیده انگلیسی


• 23 disease risk gene polymorphisms were determined in 1074 subjects.
• 5 polymorphisms displayed lower allelic frequencies in longevity subjects.
• Lack of disease risk variants contributes to longevity.

AimGenetic factors play important roles in determining human lifespan. Although some “longevity genes” have been identified to be implicated in human longevity, many disease-associated variants were also observed in the long-lived individuals. The oldest old and their offspring usually have a lower prevalence of age-related diseases, which is likely attributed to a reduction or an absence of disease risk variants.Methods and resultsTo test this hypothesis, 23 disease risk single nucleotide polymorphisms (SNPs), identified by previous genome-wide association studies (GWASs), were selected and genotyped in 1074 samples consisting of 574 longevity subjects (over 90 years old) and 500 younger controls. Our results revealed that 5 SNPs (rs2144300, rs1864163, rs2200733, rs1967017, and rs7193343) displayed significantly lower allelic frequencies and odds ratios (ORs) in the longevity group than that in the control group. The frequencies of homozygous mutation genotypes and corresponding ORs of the rs1864163, rs2200733, rs127430, rs1967017, and rs12413409 were lower in the longevity subjects. Interestingly, most of the abovementioned SNPs convey susceptibility to cardiovascular disease (CVD), which is the leading cause of deaths in old adults but shows a much lower incidence in the longevity individuals and their offspring.ConclusionTaking into account the observation that the longevity subjects and their offspring have lower rate of cardiovascular mortality, it is then most plausible that the lack of disease risk variants, especially the CVD, is a genetic contributor to longevity in the Chinese population.
