Figure 2. Manhattan plots of –log(P) for association of SNPs and chromosomal position for all SNPs analyzed in linear regression covariate-adjusted models.
Panel A presents the Manhattan plot for the phenotype, ADHD-IV Impulsivity Scale. Panel B presents the Manhattan plot for the phenotype, CBCL/1.5-5 PDPs. Panel C presents the Manhattan plot for the phenotype, CBCL/1.5-5 Total Problems. Red horizontal line represents 5×10−8 threshold for genome-wide significance. Blue horizontal line indicates the 10−6 threshold for suggestive genome-wide significance.
