I have a set of GWAS results that found significant associations in a gene I'm interested in.
I'm looking to perform mendelian randomisation using gene expression data from the GTEx dataset. The GTEx website shows me that eQTLs in this gene affect expression levels in a particular tissue.
Is there a way to download the complete expression data for these eQTLs in this tissue from GTEx so that the data can be incorporated into mendelian randomisation analysis using GCTA-GREML? I believe the exact data I need are: BETA, Standard error, and p-value.
Thanks for the help
