摘要:



文题释义:
全基因组关联分析:指在人类全基因组范围内找出存在的序列变异,即单核苷酸多态性(SNP),从中筛选出与疾病相关的SNPs。
类风湿性关节炎:是一种免疫性炎症性疾病,其病理特征包括滑膜炎症、关节软骨和骨破坏等,既往研究提示类风湿性关节炎与衰弱风险增加存在因果关系。

背景:衰弱与类风湿性关节炎均为严重影响健康的慢性疾病,随着国内人口老年化的加剧,衰弱和类风湿性关节炎等慢性病的患病率不断攀升。已有研究提示二者存在关联,但其共同的遗传基础尚不明确,因此,需进一步深入探索衰弱与类风湿性关节炎的共病遗传结构,为两种疾病的共病防治研究提供思路。
目的:探讨衰弱与类风湿性关节炎之间可能共享的遗传结构及潜在的生物学联系,为共病预防和治疗提供科学依据。
方法:采用GWAS Catalog数据库中衰弱的全基因组测序数据和芬兰数据库R11版本类风湿性关节炎的数据,应用连锁不平衡评分回归分析、贝叶斯分析、分层连锁不平衡评分回归分析评估衰弱与类风湿性关节炎的遗传相关性,多性状分析和交叉表型关联分析鉴定共享风险单核苷酸多态性,通过基因和基因集的关联分析工具、分层连锁不平衡评分回归分析方法进行组织特异性富集分析。最后,通过基于广义汇总数据的孟德尔随机化方法进行双样本孟德尔随机化分析,研究衰弱和类风湿性关节炎之间的潜在双向因果关系。
结果与结论:①衰弱与类风湿性关节炎存在显著的正遗传相关性(rg=0.28,P=4.54×10-35),尤其在特定的局部基因座区域6p21.32-21.33(chr6:31571218-33236497)中表现突出;②通过整合多种分析方法,成功识别了4个单核苷酸多态性(rs111294540,rs560607175,rs9277362,rs144112342)在衰弱与类风湿性关节炎有共享风险,分别位于HLA-DQA1、HLA-DPA1和TAP2基因;③分区基因分析揭示了112个与衰弱和类风湿性关节炎显著相关的功能元素;④结合基因表达数据,组织特异性富集分析揭示衰弱和类风湿性关节炎共同关联的单核苷酸多态性同时在脾脏中特异性富集;⑤此外,孟德尔随机化验证了衰弱和类风湿性关节炎之间的双向因果关系;⑥此次研究解析了衰弱与类风湿性关节炎的共同遗传基础,发现两种疾病存在显著的遗传相关性和共同的风险基因,并验证了二者的双向因果关系,为未来探索二者共病机制和治疗靶点提供参考;此次研究虽采用欧洲人群数据,但是对国内人口老龄化逐渐加剧社会背景下的慢病防治具有借鉴和参考意义。

Abstract: BACKGROUND: Frailty and rheumatoid arthritis are both chronic diseases that seriously impact health. With the accelerating aging population in China, the prevalence of chronic diseases such as frailty and rheumatoid arthritis continues to rise. Existing studies have suggested an association between the two, but their shared genetic basis is still unclear. Therefore, further in-depth exploration of the comorbid genetic structure of frailty and rheumatoid arthritis is necessary to provide insights into co-morbid prevention and treatment of the two diseases.
OBJECTIVE: To explore the possible shared genetic structure and potential biological links between frailty and rheumatoid arthritis, and to provide a scientific basis for co-morbidity prevention and treatment.
METHODS: We utilized whole-genome sequencing data for frailty from the GWAS Catalog database and rheumatoid arthritis data from the FinnGen R11. Linkage disequilibrium score regression analysis, Bayesian analysis, and stratified linkage disequilibrium score regression analysis were employed to assess the genetic correlation between frailty and rheumatoid arthritis. Multi-trait analysis and cross-trait meta-analysis were used to identify shared risk single nucleotide polymorphisms. Gene and gene-set association analysis tools and stratified linkage disequilibrium score regression analysis were applied for tissue-specific enrichment analysis. Finally, two-sample Mendelian randomization analysis based on generalized summary data was conducted to investigate potential bidirectional causal relationships between frailty and rheumatoid arthritis.
RESULTS AND CONCLUSION: Frailty and rheumatoid arthritis exhibited significant positive genetic correlation (rg=0.28, P=4.54×10-35), particularly in specific loci at 6p21.32-21.33 (chr6:31571218-33236497). Through integrating multiple analytical methods, we successfully identified four single nucleotide polymorphisms (rs111294540, rs560607175, rs9277362, rs144112342) that shared risk between frailty and rheumatoid arthritis, located in the HLA-DQA1, HLA-DPA1, and TAP2 genes. Functional element analysis revealed 12 significant elements associated with both frailty and rheumatoid arthritis. Combined with gene expression data, tissue-specific enrichment analysis showed that single nucleotide polymorphisms associated with both frailty and rheumatoid arthritis were specifically enriched in the spleen. Furthermore, Mendelian randomization validated the bidirectional causal relationship between frailty and rheumatoid arthritis. This study elucidated the shared genetic basis between frailty and rheumatoid arthritis, revealing significant genetic correlation and common risk genes for both diseases, and validating their bidirectional causal relationship. These findings provide a reference for the future exploration of the comorbidity mechanisms and therapeutic targets for the two conditions. Although this research utilized data from European populations, it holds valuable implications for the prevention and treatment of chronic diseases in the context of the increasingly aging population in China.
