多基因评分(PGS)汇总了整个基因组中变异的影响,以估计遗传易感性,但在外部研究人群中的表现较低。Ding等人的一项新研究应用了一种新的框架来估计PGS的个体水平预测准确性,并证明了性能下降与遗传距离呈线性关系。
Polygenic scores (PGSs) aggregate the effects of variants across the genome to estimate genetic liability, but have lower performance in external study populations. A new study by Ding et al. has applied a novel framework to estimate the individual-level predictive accuracy of PGSs, and demonstrates that performance reduction occurs linearly with genetic distance.
