美国黑人患慢性肾脏病的单祖先与多祖先多基因风险评分。
背景:慢性肾脏病(CKD)是心血管疾病和早期死亡的风险因素。最近,多基因风险评分(PRS)被用来量化慢性肾脏病的风险。然而,非洲血统人群在 CKD 遗传研究和 PRS 整体开发中的代表性不足。此外,欧洲血统的 PRS 在非洲血统人群中的预测性能也有所下降:本研究旨在为美国黑人制定 CKD PRS。我们从 "百万退伍军人计划"(MVP)和 "中风的地理和种族差异原因"(REGARDS)研究中的估计肾小球滤过率(eGFR)全基因组关联研究(GWAS)的荟萃分析中获得了评分权重,从而开发出了eGFR PRS。我们在高血压遗传流行病学网络 (HyperGEN) 的参与者队列中优化了 PRS 风险模型。我们还在精准医学跨奥美病学联盟(TOPMed)和高血压相关治疗遗传学研究(GenHAT)的黑人参与者子集中进行了验证:定义为 3 期或 3 期以上的 CKD 患病率与 PRS 呈连续预测关系(OR[95% CI]:1.35[1.08,1.68]),且呈阈值依赖关系。此外,将 APOL1 风险状态(一种在撒哈拉以南非洲后裔中发病率较高的 CKD 潜在变异体)包括在内可提高评分的准确性。PRS 与传统的 CKD 风险因素以及基于先前的 eGFR 方程的 CKD 分类的敏感性分析结果一致。与之前发表的 PRS 相比,我们的 PRS 预测性能与欧洲血统的肾脏特征 PRS 不相上下。然而,这两种单一宗族的 PRS 预测性均低于多宗族衍生的 PRS:在这项研究中,我们开发了一种与慢性肾脏病有显著相关性的 PRS,当包括 APOL1 风险状况时,其预测准确性有所提高。然而,在我们的研究中,从多祖先群体中得出的 PRS 优于单祖先 PRS。

期刊介绍: The Journal of the American Society of Nephrology (JASN) stands as the preeminent kidney journal globally, offering an exceptional synthesis of cutting-edge basic research, clinical epidemiology, meta-analysis, and relevant editorial content. Representing a comprehensive resource, JASN encompasses clinical research, editorials distilling key findings, perspectives, and timely reviews. Editorials are skillfully crafted to elucidate the essential insights of the parent article, while JASN actively encourages the submission of Letters to the Editor discussing recently published articles. The reviews featured in JASN are consistently erudite and comprehensive, providing thorough coverage of respective fields. Since its inception in July 1990, JASN has been a monthly publication. JASN publishes original research reports and editorial content across a spectrum of basic and clinical science relevant to the broad discipline of nephrology. Topics covered include renal cell biology, developmental biology of the kidney, genetics of kidney disease, cell and transport physiology, hemodynamics and vascular regulation, mechanisms of blood pressure regulation, renal immunology, kidney pathology, pathophysiology of kidney diseases, nephrolithiasis, clinical nephrology (including dialysis and transplantation), and hypertension. Furthermore, articles addressing healthcare policy and care delivery issues relevant to nephrology are warmly welcomed.
