A Table of all published EWAS with deep molecular phenotypes (omics)

posted in: Resources

The number of genome-wide association studies (GWAS) with deep molecular phenotypes, especially metabolomics and proteomics, is rapidly increasing. On other places of this blog I maintain tables of published GWAS with metabolomics (mQTLs), proteomics (pQTLs), and DNA methylation (meQTLs).

Here I extend this collection by a table of all published epigenome-wide association studies (EWAS) with metabolomics, proteomics, and other deep molecular phenotypes. I include studies with a smaller set of traits (e.g. blood lipids) if they are of interest due to their large sample size and findings (i.e. reporting loci that overlap with multiomics traits).

Please read our review Connecting the epigenome, metabolome and proteome for a deeper understanding of disease (Suhre et al., J. Int. Medicine, 2021).
