Manhattan plot combining association results from 7,123,928 random-effects meta-analyses based on a PDGene datafreeze of April 15th 2011. Many of the GWAS SNPs were imputed using the IMPUTE (v2.0) software based on HapMap (Rel #3) and 1000 Genomes Project (Pilot release, June 2010) European-descent reference panels. Sample-specific association results were computed with SNPTEST (v2.2), meta-analyses were performed in PLINK (v1.07). Meta-analysis results are plotted as -log10 P-values (y-axis) against physical chromosomal location (x-axis). Black and grey dots indicate results originating exclusively from GWAS datasets, while green dots are based on a combination of candidate- gene studies, supplemented by GWAS datasets (where applicable). Note that the y-axis is truncated at 1.0E-25 for better legibility. The plot was generated in R using "qqman".
