While atherosclerotic cardiovascular disease (ASCVD) is known to be common among modern people exposed to various risk factors, recent paleopathological studies have shown that it affected ancient populations much more frequently than expected. In 2010, we investigated a 17th century Korean female mummy with presumptive ASCVD signs. Although the resulting report was a rare and invaluable conjecture on the disease status of an ancient East Asian population, the diagnosis had been based only on anatomical and radiological techniques, and so could not confirm the existence of ASCVD in the mummy. In the present study, we thus performed a paleogenetic analysis to supplement the previous conventional diagnosis of ASCVD. In aDNA extracted from the same Korean mummy, we identified the risk alleles of seven different SNPs (rs5351, rs10757274, rs2383206, rs2383207, rs10757278, rs4380028 and rs1333049) that had already been revealed to be the major risk loci of ASCVD in East Asian populations. The reliability of this study could be enhanced by cross-validation using two different analyses: Sanger and SNaPshot techniques. We were able to establish that the 17th century Korean female had a strong genetic predisposition to increased risk of ASCVD. The current paleogenetic diagnosis, the first of its kind outside Europe, re-confirms its utility as an adjunct modality for confirmatory diagnosis of ancient ASCVD.
虽然已知动脉粥样硬化性心血管疾病(ASCVD)在暴露于各种风险因素的现代人中很常见,但最近的古病理学研究表明,它对古代人群的影响比预期更为频繁。2010年,我们调查了一具具有疑似ASCVD体征的17世纪韩国女性木乃伊。尽管所得报告是对古代东亚人群疾病状况的罕见且宝贵的推测,但诊断仅基于解剖学和放射学技术,因此无法确认木乃伊中是否存在ASCVD。因此,在本研究中,我们进行了古遗传学分析,以补充先前对ASCVD的传统诊断。在从同一具韩国木乃伊提取的古代DNA中,我们鉴定出七个不同单核苷酸多态性(SNP,rs5351、rs10757274、rs2383206、rs2383207、rs10757278、rs4380028和rs1333049)的风险等位基因,这些等位基因已被证明是东亚人群中ASCVD的主要风险位点。通过使用两种不同的分析方法(桑格测序法和SNaPshot技术)进行交叉验证,可以提高本研究的可靠性。我们能够确定这位17世纪的韩国女性具有患ASCVD风险增加的强烈遗传易感性。目前的古遗传学诊断是欧洲以外的首例此类诊断,再次证实了其作为古代ASCVD确诊诊断辅助手段的效用。
