Figure 1: Genome-wide association plot for thyroid cancer.

The Manhattan plots of genome-wide association signals with (a) DTC and (b) PTC for stage 1. The x-axis represents the SNP markers on each chromosome. The y-axis shows the −log10 P-value (logistic regression). The red horizontal line represents the genome-wide significance threshold P=5.0 × 10−8, and the blue horizontal line represents the genome-wide suggestiveness threshold P=1.0 × 10−6. Eleven candidate loci of DTC, PTC or FTC are shown in green.
