a-c, Signals in candidate genes identified on the basis of
the mouse phenotypes of abnormal GFR (a), abnormal kidney
physiology (b) and abnormal kidney morphology (c). The
y axis shows −log10 (P)
for association with eGFR in the trans-ancestry meta-analysis for the variant
with the lowest P value in each candidate gene. The dashed line
corresponds to genome-wide significance (P =
5×10−8), and the solid gray line corresponds to the
experiment-wide significance threshold for each nested candidate gene analysis.
Orange, genome-wide significance; red, experiment-wide but not genome-wide
significance; blue, no significantly associated SNPs. Genes are labeled if they
reached experiment- but not genome-wide significance; black font indicates genes
not mapping to loci reported in the main analysis. Enrichment P
values correspond to the observed number of genes with association signals below
the experiment-wide threshold against the number expected on the basis of the
complementary cumulative binomial distribution (Methods).
