泛种族孕前筛查:来自遗传多样性人群的大规模计划的证据。
背景:孕前遗传筛查是识别遗传疾病高危夫妇(arc)和支持知情生殖决策的关键预防策略。然而,不断增加的人口混合和下一代测序的广泛采用挑战了祖先驱动的风险分层的有效性。方法:共有107 739人参加了国家筛查计划,其中51 722对夫妇和4295人独立检测,代表33个民族。在顺序检测策略下,所有女性都进行了初步筛查,而男性伴侣只有在女性伴侣中发现致病变异(PV)时才进行检测。因此,76 317人的携带者状态结果可用。结果:76 317人中,30 475人(39.9%)携带至少一种PV。在1.15%的夫妇中发现了arc,在某些种族群体中高达10%。共同祖先的风险增加,同祖先夫妇的风险增加到5.72%,而混合祖先夫妇的风险增加到1.28% (OR 4.69; 95% CI 3.70至6.01)。与基于种族的筛查相比,泛种族靶向常见变异(TCV)筛查方法鉴定出的arc多11.9%,其中26.8%的变异在其历史相关人群之外检测到。实施后的分析还发现了产量有限的变体,支持周期性的面板改进。结论:与基于种族的方法相比,TCV方法改善了携带者和ARC的检测,代表了一种实用的遗传多样性人群筛查模型。这些发现支持将TCV方法作为遗传多样性人群的实用筛查策略的考虑,通过持续的小组改进、包容性参考数据集和有针对性地向高风险社区推广,以最大限度地提高其人群影响。
