Distributions of genomic functional categories of cancer GWAS LD80 SNP sets. For each SNP in the corresponding GWAS LD80 SNP set, the genomic functional category was determined based on genomic annotation, and the overall proportions were shown in the plot. Categories included coding, 5′ untranslated and 3′ untranslated portions of exons, as well as intronic, intergenic and upstream or downstream proximals (within 10 kb of the TSSs or TTSs). The distribution of Illumina 660K SNP array was presented as a background. Numbers above the chart showed the corresponding total SNP counts of each LD80 SNP set.
