Extended Data Fig. 3: Estimated inflation of association plots excluding the MHC region.

QQ plots of the variants tested for association using linear mixed model regression in each individual population and tested antibody response, with the extended MHC region excluded (chromosome 6, 25.5-34 Mb, build 37). The x-axis is the expected P-value and the y-axis is the observed with all points representing the tested genetic variants.
