For example, protein levels of SERPINF1 showed MR evidence to support a putative causal effect on stroke in African ancestry (p = 3.76 × 10−5) but showed little evidence of an effect in European ancestry (p = 0.83) (see Table S16B, the full results could be queried using the EpiGraphDB web application). This evidence concerns the gene SERPINF1 and Stroke.
