WebTwo GWAS/eQTL variant pairs that were classified as colocalized only by conditional analysis had marginal COLOC PP4 probabilities (PP4 0.66 for C3orf78 and 0.76 for STC1). However, we expect that the priors we selected for COLOC will be conservative; when we increased the prior probability that a variant is causal to both GWAS and eQTL to … WebMar 29, 2024 · GWAS–eQTL colocalization methods such as Sherlock 8, coloc 9,10, QTLMatch 11, eCaviar 12, enloc 13 and RTC 14 are also vulnerable.

WebSep 11, 2024 · Finally, we identify a small subset of eQTL-associated variants highly correlated with local ancestry, providing a resource to enhance functional follow-up. Conclusions: We provide a local ancestry map for admixed individuals in the GTEx v8 release and describe the impact of ancestry and admixture on gene expression, eQTLs, … WebNov 9, 2024 · Summary Identifying genomic features responsible for genome-wide association study (GWAS) signals has proven to be a difficult challenge; many researchers have turned to colocalization analysis of GWAS signals with expression quantitative trait loci (eQTL) and splicing quantitative trait loci (sQTL) to connect GWAS signals to candidate … WebMay 17, 2024 · In simulations in which we vary sample size of the GWAS and eQTL datasets, we find reduced performance of POEMColoc-1 relative to coloc as GWAS sample size is reduced, and POEMColoc-2 as both eQTL and GWAS sample size are reduced, suggesting sample size in the imputed dataset has an important effect on performance … can you plant orchids outside
