Summary
This paper presents whole-genome sequencing of 490,640 UK Biobank participants, substantially expanding on prior genotyping efforts to enable unbiased discovery of genetic variation across the full genome. By coupling sequencing data with rich phenotypic records, the authors identified novel genetic associations with disease traits across multiple ancestry groups, with particular strength in European-ancestry individuals but also significant findings in African and Asian ancestry populations. The dataset's improved capacity to detect structural variants and coding/non-coding exonic variation strengthens precision medicine and therapeutic discovery potential.
UK applicability
As this represents the UK Biobank's core sequencing resource, the findings are directly applicable to UK-based genetic and precision medicine research. The predominance of European-ancestry associations reflects the UK Biobank's demographic composition and underscores the need for broader ancestry representation in future sequencing efforts to ensure equitable precision medicine outcomes.
Key measures
Whole-genome sequencing variants; within- and cross-ancestry genomic associations with disease traits; comparison of structural variant and exonic variation detection versus whole-exome sequencing
Outcomes reported
The study reports whole-genome sequencing data from 490,640 UK Biobank participants, enabling identification of genetic associations with disease traits across multiple ancestries. The dataset strengthens understanding of structural variants, exonic variation, and coding/UTR sequences compared to whole-exome sequencing approaches.
