Researchers found ancestry-specific risk variants and developed a better polygenic risk score based on a GWAS and subsequent meta-analysis.

In Nature this week: genome-wide association study of 42 diseases among Japanese population, transfer RNA modifications, and more.

The GWAS of more than 200,000 Japanese individuals across 42 diseases identified 25 novel loci shared between Japanese and European populations.

Both studies emerged from the ongoing Human Cell Atlas project and could help scientists decide on the best approaches to use in various contexts.

The effort is focused on building an atlas of immune cell types found across a range of Asian population groups as part of the Human Cell Atlas project.
