Manhattan plot of the X chromosome meta-analysis results of three genome-wide association studies. The x-axis is position (kb) on the X chromosome, and the y-axis is the P value (− log10 P) for cross-population X chromosome meta-analysis. Known systemic lupus erythematosus susceptibility genes are labeled in blue, and the gene including the novel loci (rs13440883) is labeled in red. The dashed lines indicate the suggestive P value (1 × 10− 5, blue) and the genome-wide significant P value (5 × 10− 8, red)
