摘要
In a recent study published in Nature Medicine,Smith and colleagues used data from 1.4 million individuals across 37 genome-wide association studies(GWAS)reflecting different genetic ancestral populations to identify 12 genetic clusters,mostly shared among the different populations,and associated the weighted sums of genetic variants of each cluster—termed as partitioned polygenic scores(pPSs)—with various lab-based,anthropometric and cardiometabolic traits.Their analyses extended previous studies on biological mechanisms linking genetics to type 2 diabetes(T2D)risk and pointed to both similarities of genetic clusters across multiple populations and differences regarding their contributions to overall T2D risk among different ethnicities.
