Using tissue- and ancestry-aware causal inference analyses, we identified 923 genes and 46 proteins whose expression levels causally influence type 2 diabetes risk. Tissue-related heterogeneity was high, whereas ancestry-related heterogeneity was low, although some effects were observed only in non-European populations. These results underscore the need to investigate disease-relevant tissues and diverse populations.
