Figure 2

Regional-association plots displaying rs9875793 and the SCL2A2 SNPs. Allelic χ2 test P values from SNPs are plotted against positions from the March 2006 human reference sequence, annotated by RefSeq genes. The most highly associated marker from the combined analysis (P) is indicated by an enlarged red diamond, which is in the center of a genomic window of around 300 Mb. The strength of linkage disequilibrium (in r2) between the top SNP and its adjacent markers is demonstrated by the red (high) to white (low) color bar (top right corner).
