Arruda AL et al., Cell Genomics - A commentary calling for generation of tissue-specific molecular data across diverse ancestries to improve fine-mapping, causal inference, and equitable translation of GWAS findings beyond Eurocentric and blood-focused resources. Key terms: genomic equity, multi-ancestry, molecular QTL, tissue-specific, GWAS.
Study Highlights:
The authors document pervasive Eurocentric bias across GWAS and molecular QTL resources and note that most available molecular data with genetics are derived from blood. They argue that tissue-specific regulatory variation and ancestry differences in linkage disequilibrium require primary-tissue multi-ancestry molecular datasets to resolve noncoding GWAS signals. GTEx and other initiatives contribute valuable data but have limited non-European sample sizes and incomplete ancestry metadata, constraining colocalization and causal inference. The commentary calls for targeted funding, infrastructure, community engagement, and global collaboration to generate diverse tissue molecular data.
Conclusion:
To achieve equitable and translatable genomics, the field must prioritize generation of tissue-specific, multi-ancestry molecular datasets, improve ancestry metadata, and invest in methods and partnerships that enable inclusive fine-mapping and functional interpretation.
