Chromosome 6 lead variant across the contributing studies and ancestries in GWAS meta-analyses of long COVID with strict case definition and broad control definition. Lead variant rs9367106 (solid line) and if missing, imputed by the variant with the highest LD with the lead variant for illustrative purpose, that is, rs12660421 ( r = 0.98 in European in 1,000 G + HGDP samples 55 , dotted lines). For the imputed variants, was weighted by multiplying by the LD correlation coefficient ( r = 0.98). Centre, OR; error bar, 95% CI. Genetic ancestries marked by colors. MAF varies across ancestries, ranging from 1% to 34% (Supplementary Fig. 4 ). AFR, African; AMR, Admixed American; EAS, East Asian; EUR, European; UKBB, UK Biobank. (Results for the other three GWAS meta-analyses in Supplementary Figs. 2 and 3a–c ).
