Figure 5. Partitioning of heritability across functional classes in prostate cancer.
Visual representation of heritability enrichment in three studies a,b: iCOGS; c: AAPC; d: BPC3 (shown numerically in Table 1). Each subplot corresponds to an analysis of the listed joint model, with coloured slices representing the functional annotations evaluated. Volume of each interior (light coloured) pie-chart slice represents the %SNP for the functional annotation, which is equal to the expected under the null of no enrichment. Volume of each shaded pie-chart slice represents the actual
inferred by the model. Slices extending outside/inside the middle pie correspond to enrichment/depletion in SNP heritability, as indicated by the dotted lines. Colour coding is consistent across all subpanels. * (**) denotes significant deviation at P<0.05 (P<0.05/15) of fraction of SNP heritability (
from null model of
by Z-test; see Supplementary Table 6 for P values).
