基于人群的队列中基因组结果的返回和总体外显率 (PopSeq)

2026年7月8日 更新者:Robert C. Green, MD, MPH、Brigham and Women's Hospital
PopSeq 项目是一项前瞻性队列研究,将在弗雷明汉心脏研究 (FHS) 和杰克逊心脏研究 (JHS) 队列中开发和实施基因组结果返回 (gRoR) 流程,并探索相关的医学、行为和经济结果。 该研究将解释 JHS/FHS 参与者的基因组序列,这些参与者之前由 TOPMed 测序,他们同意基因组返回结果和/或基因测试。 我们将开发和应用用于基因组变异的可扩展筛选/分类的新方法,并将通过对 FHS 和 JHS 的一部分参与者进行表型分析来探索基因组外显率。

研究概览

详细说明

该项目的目标是:1) 将临床上可操作的基因组结果返回给参与者并跟踪结果。 在同意 gRoR 的活着的 FHS/JHS 参与者中,我们将联系那些在 ACMG 推荐的次要发现列表中指出的基因之一发现有害的可操作变异的人(估计 2% 的参与者)。 2) 改进识别有效致病变异的高通量方法。 改进和应用 FHS/JHS 基因组的高通量筛选方法,以保持高灵敏度检测约 3500 个孟德尔疾病相关基因的有害变异,同时降低非致病性/可能致病性变异的错误发现率。 3) 探索孟德尔疾病的总外显率。 查看来自 FHS 和 JHS 参与者子集的表型数据,并将其与基因型数据进行比较。

要收集的数据包括同意 gRoR 和得知他们在 ACMG 列出的基因之一中具有有害变异的个体的结果和表型数据。 这些数据将通过调查自行报告,并将审查可用的医疗记录。 可以收集和审查其他不可操作的孟德尔疾病基因的其他表型数据,以探索基因组外显率。

被确定在可操作基因中具有有害变异的研究参与者可能会从了解此信息中获得直接的健康益处;然而,将基因组结果返回给未出现医学指征的健康个体可能会造成意想不到的危害,这与筛查和管理中的变异定向增加有关。 本研究的重点是探索与基于人群的队列中返回基因组信息相关的好处和任何潜在危害。 它还将使我们能够更好地了解这些变异在未选择疾病状态的两个人群中的外显率,并使我们能够比较主要是非裔美国人人群与高加索人群的结果。 开发简化变异分析的方法将有助于提高实验室效率,并将推动变异管理和分析领域的发展。

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Follow Through With Disclosure
大体时间:From genetic result notification to 8 months post-disclosure
Living JHS/FHS participants sequenced as part of the TOPMed program who were notified about an actionable genetic result that warranted having the research result verified who followed through with having their result confirmed and disclosed to their health care provider.
From genetic result notification to 8 months post-disclosure
Total Costs of Program Implementation
大体时间:From the initiation of bioinformatics analysis to disclosure of confirmed actionable genetic finding (approximately 6 months).
We will determine the costs and associated time demands of implementing gRoR using a microcosting approach in which study staff track the amount of time they spend and the resources they use for each step of the protocol. Ranges are based on 50% to 200% of point estimates given variability in wages and prices of services.
From the initiation of bioinformatics analysis to disclosure of confirmed actionable genetic finding (approximately 6 months).
Costs of Follow-Up Care
大体时间:1 Year Post-Disclosure Survey (from 12 months to 15 months after disclosure of confirmed results)
For follow-up medical care, we use a gross costing approach where we apply Centers for Medicare and Medicaid fee schedules to participant-reported referrals and tests.
