I am just dip my feet into the GWAS field. I got the GWAS summary data in Chinese population. I do not have the expression data on the same population. so I wanna conduct the colocalization analysis using eQTL from GTEx. As I known, GTEx(v8) includes up to 17% of individuals with non-European or admixed ancestry, including 103 African American and 12 Asian American individuals who have both whole genome sequencing and gene expression data. Could I perform the colocalization analysis using the GWAS summary data in Chinese population and all eQTL from GTEx?
