Cross-ancestry Comparison of Colocalized GWAS-eQTL Signals
Locus plots showing the regional associations for BMI in Japanese individuals,61 colored by East Asian LD (EAS) (top) and gene expression in Finns (bottom), colored by Finnish LD.
(A) A DAP3 eQTL signal is colocalized with a BMI signal near GON4L. The lead variant is shared between the GWAS and eQTL studies and the patterns of association are similar.
(B) A SULT1A2 eQTL signal is colocalized with a BMI signal near IL27/NUPR1. The LD between the lead eQTL and GWAS variants is low in East Asians (r2 = 0.22) but high in Finns (r2 = 0.93).
