Figure 2. LD among the four significant SNPs from NGRC conditional analysis and the most significant HLA SNPs from other PD GWAS's.

LD was measured as D′ (panel A) and as r² (panel B). NGRC SNPs are numbered 1–4 and marked in red frame. The most significant HLA SNP from other GWAS's are indicated by rs number and the study name. Numbers in cells are % D′ (panel A) and % r² (panel B). Red cell without a number reflects D′ = 1, blue cells without a number reflect D′ = 0.
