QQ-plot of the GWAS analysis on the individuals of the Protected exposure for the four phenotypic traits investigated. The probability distribution Observed for each of the 819 tested SNPs is plotted against the probability distribution Expected under the null model. Outliers points are SNPs with observed P values more significant than expected under the null hypothesis for the investigated trait
