Abstract
Population-scale metabolomics studies have linked metabolic measures to diseases, quantitative traits, and genetic variation, but the results are scattered across assay platforms, phenotype definitions, and analytical formats. MetabDB integrates 16 public studies spanning nuclear magnetic resonance, mass spectrometry, and lipidomics. The current release contains 2663 metabolic measures, 3524 diseases and outcomes, 3382 other genome-wide association traits, and 2025 molecular quantitative trait locus (QTL) targets. MetabDB links genomic variants, genes and proteins, metabolic measures, and diseases or traits through variant/QTL associations, fine-mapping, rare-variant or burden analyses, colocalization, Mendelian randomization, and population associations. Metabolic measures areretained in their source-reported forms, including compounds, lipid species, lipoprotein measures, ratios, percentages, and derived traits. Gene- and protein-level evidence can be examined alongside genomic signals and related disease or trait evidence for the same metabolic measure. Source information and reported analytical details are retained, including the source study, original variable or phenotype definition, assay, unit, exposure scale, analytical model, and statistics where available. Search, browse, and colocalization pages, together with gene evidence breadth and disease-association profiles, provide access to these records. MetabDB is freely available at http://www.mulinlab.org/metabdb/.
