Effects of genetic variants in CR1 on sCR1 protein levels. A, B The minor allele (G) at rs6691117 was significantly associated with a decrease in sCR1, while the minor (A) allele at rs6656401 was strongly associated with increased sCR1 levels in plasma. Data are shown as mean ± SD and were analysed using Kruskal–Wallis with Dunn’s multiple comparisons post-hoc tests. *p < 0.05; **p < 0.01; ***p < 0.001. Numbers for homozygote and heterozygote carriers of each SNP are shown in Table 1. C Manhattan plot of GWAS results on the whole sample set (n = 1667) with plasma sCR1 as endophenotype identifies multiple loci in the CR1 gene on chromosome 1 significantly associated with changes in plasma sCR1 levels. D, E LocusZoom plots in the region identify a cluster of significant SNPs in high LD with rs6656401 (D), while rs6691117 was below the significance threshold (E)
