Where available, we show confidence intervals for the beta or odds ratio estimates of variant associations.
In some cases, we may not show a value for beta or odds ratio when the variant is palindromic (A vs T SNPs, or C vs G), in which case we can’t be sure what the correct sign of the odd ratio is. In general, this only happens for studies that don’t have summary statistics, i.e. where the associations come from GWAS Catalog curation only.
Beta and odds ratio are not given for all the studies involving a specific variant. From Open Targets Genetics
