Results from the meta-analysis of SRE scores are displayed in Figures 1 and 2. In each group-level analysis and in the meta-analysis, there was no evidence of inflation due to population stratification (λ1000=0.99–1.00). A total of 15,642,250 markers were analyzed in the meta-analysis; 10,752,408 were assessed in at least 1000 individuals. No individual locus met genome-wide significance criteria (p<5×10−8). The top marker was rs146298733 (p=3.16×10−7), which maps to an intron in DLGAP1 on chromosome 18; this result may be spurious as surrounding markers do not have similar p-values. The minor allele was only of sufficient frequency to test in the ALSPAC and EUR groups (N=6039; MAF=0.02 in both samples).
