遗传补偿是提高全基因组关联(GWA)研究能力和分辨率的一种经济高效的方法。目前可公开访问的分配参考小组准确地预测了不同人群中常见的等位基因频率(MAF)为≥5%的变异和低频变异(0.5MAF<；5%)的基因型，但罕见变异(MAF<；0.5%)的归属仍然相当有限。在目前的研究中，我们评估了来自不同人群的参考小组与基于人口特定的高覆盖率(30倍)全基因组测序(WGS)的参考小组所实现的归因准确性，该参考小组包括2244名爱沙尼亚人(占爱沙尼亚成年人的0.25%)。尽管爱沙尼亚特有的专家小组包含的单倍型和变异较少，但归因于低频和罕见变异的可信度和准确性要高得多。这一结果表明了特定人群参考板在人类遗传学研究中的实用性。
Genetic imputation is a cost-efficient way to improve the power and resolution of genome-wide association (GWA) studies. Current publicly accessible imputation reference panels accurately predict genotypes for common variants with minor allele frequency (MAF)≥5% and low-frequency variants (0.5≤MAF<5%) across diverse populations, but the imputation of rare variation (MAF<0.5%) is still rather limited. In the current study, we evaluate imputation accuracy achieved with reference panels from diverse populations with a population-specific high-coverage (30 ×) whole-genome sequencing (WGS) based reference panel, comprising of 2244 Estonian individuals (0.25% of adult Estonians). Although the Estonian-specific panel contains fewer haplotypes and variants, the imputation confidence and accuracy of imputed low-frequency and rare variants was significantly higher. The results indicate the utility of population-specific reference panels for human genetic studies.
