Expanded gene network of AD-risk loci. (A) Circos plot of AD GWAS loci,
showing microglia enhancers (gold bars), promoters (turquoise), open chromatin
regions (black bars) and PLAC-seq interactions (black loops). Dots show z-score
values of high-confidence AD variants identified by fine mapping (Kunkle, stage
1) with log10 p-value < 6e-5 (18).
Blue dots represent z-score values of the credible set of AD SNPs (95%
confidence); red lines show 15 high-confidence AD SNPs with a posterior
probability > 0.2. (B) Chow-Ruskey plot of genes that are GWAS-assigned
and PLAC-seq linked to AD-risk credible set variants in microglia, neurons and
oligodendrocytes. (C)-(E) UCSC browser of interactions at AD-risk loci
demonstrating (C) reassignment of GWAS-assigned genes, (D) extension of
GWAS-assigned genes and (E) cell type-specific gene regulatory regions. The AD
GWAS track shows meta-analysis p-values of stage 2 variants (18); line indicates p-value = 5e-8; blue dots are
fine mapped 95% credible set variants.
