Q-Q plot for Sleep Clinic SNPs. The ranked observed and randomly-expected linear regression probabilities (P values) are plotted for the Sleep Clinic SNPs on a negative log10 scale. Higher values indicate smaller P values with greater significance. The three upper SNPs (from left to right) are FMR1 rs28900, rs25714, and rs25702. The red line indicates the expected trend were there no genomic inflation.
