  1. *The gene closest to the variant and other candidate genes are listed (index gene).
  2. §R2 information was extracted from 1000 Genomes Project Phase 3 in European (EUR) population.
  3. Effect sizes in the replication studies are based on semi-quantitative metabolomics measurements of 1,5-AG9 and are thus on a different scale compared to the discovery estimates.
  4. #rs13229622 is an independent SNP with genome-wide significant association with 1,5-AG found through conditional analysis. It was not investigated in the metabolite GWAS because available association results were not conditional estimates.
  5. A1 is the effect allele, i.e. the allele for which effect estimates are provided. Abbreviations: Repl SNP = replication SNP; AF = effect allele frequency; SE = standard error.
