Genome-wide association results and detailed peak association regions.

<p>(<b>A</b>) Manhattan plot of the meta-analysis performed on early-onset bipolar patients and controls from France and Germany. Physical position is shown along the <i>x</i> axis and –log10(<i>P</i>-value) is shown along the <i>y</i> axis. (<b>B</b>) Detail of the two most associated regions on chromosomes 5p13 and 12p12. Allele frequency differences are represented by –log10(<i>P</i>-values) for the French (open grey circles), the German (open grey squares) and the meta- (open red diamonds) analyses. Grey crosses represent –log10(<i>P</i>-value) for imputed ungenotyped SNPs. The most associated SNP for each region is shown with orange circle. On chromosome 12p12, the lowest <i>P</i>-value (<i>P</i> = 2.1×10⁻⁷) was observed for an imputed SNP (<i>rs10743315</i>). On chromosome 5p13, the lowest <i>P</i>-value (<i>P</i> = 2.6×10⁻⁷) was observed for a three-SNPs window haplotype (light blue line) located downstream to <i>OXCT1</i> and upstream to <i>PLCXD3</i> (<i>rs624097-rs316762-rs10512793</i>). The genome-wide significant threshold (<i>P</i> = 5×10⁻⁸) is indicated by the blue dash line and the dot black line shows a threshold at <i>P</i> = 5×10⁻⁵. The largest differences in allele frequencies are represented with filled diamonds. Gene position and annotation (<a href="http://genome.ucsc.edu/" target="_blank">http://genome.ucsc.edu/</a>) are symbolised by green arrows. Linkage disequilibrium (r²) estimated according to HapMap CEU population SNPs (release 3) is symbolised in the bottom part of each figure. Darker red indicates higher values.</p
