LocusZoom plots showing genome-wide significant associations observed in the meta- analysis.

<p>(A) The observed association for maximal cranial width (MCW) at 15p11.2 and (B) maximal cranial length (MCL) at 17q11.2. LocusZoom plots show the association (left y-axis; log10-transformed p-values) with facial traits. Genotyped SNPs are depicted by asterisks and imputed SNPs are depicted by circles. Shading of the points represent the linkage disequilibrium (r², based on the 1000 Genomes Project Europeans) between each SNP and the top SNP, indicated by purple shading. Grey points in these plots represent the lack of LD information between the index SNP (diamond) the plotted SNP (circle or asterisk). The blue overlay shows the recombination rate (right y-axis). Positions of genes are shown below the plot.
