Figure 2From: Associations between SNPs in candidate immune-relevant genes and rubella antibody levels: a multigenic assessmentQuantile plot of observed versus expected p-values (on the logarithmic scale) for the associations between the combinations formed from each possible pair of SNPs and rubella antibody levels. While the observed p-values depart somewhat from the line of unity, they do not follow a pattern that suggests the presence of major epistatic effects.Back to article page
