1098-百万级多样化人群血脂外显子组关联研究

from 聊聊Sci

这项研究通过对来自不同族裔的115.8万名受试者进行外显子组关联分析,系统地揭示了罕见编码变异对血脂水平的影响。研究团队从近300万个变异中识别出800个具有显著统计学意义的关联,这些变异对脂质代谢异常及冠状动脉疾病(CAD)的遗传诊断具有重要价值。通过纳入超过23万名非欧洲裔个体,该研究填补了以往基因研究在人群多样性上的空白,证明了许多致病变异在不同族裔间具有高度一致的作用效应。研究不仅发现了多个与血脂相关的新基因位点,还证实了通过抑制RORC基因可能成为降低低密度脂蛋白胆固醇的新型药物靶点。此外,该成果为临床重新评估家族性高胆固醇血症(FH)变异的致病性提供了关键证据,有助于实现更精准的疾病风险预测与诊疗。References:Koyama, S., Yu, Z., Choi, S.H. et al.
