A Table of all published GWAS with DNA methylation

posted in: Resources | 0

The number of association studies of DNA variation with CpG methylation – especially based on the Illumina 450k array – is steadily increasing. Quantitative trait loci for intermediate traits are particularly interesting to serve as instruments in Mendelian Randomization studies. On other places on this blog I maintain tables of published GWAS with metabolomics (mQTLs) and proteomics (pQTLs). Here you find a similar collection of studies that contain large numbers of DNA methylation QTLs (meQTLs). Should you know of any study missing here, please let me know.
