Genetic association of SNPs in the leukotriene pathway genes with chronic rhinosinusitis. Each subfigure presents the result of one gene. The top line indicates the gene name and symbol. The upper part of each subfigure shows the exon-intron structure of the gene and the localization of the genotyped SNPs. The coding exons are shown in black and the untranslated regions are shown in grey. The lower part of each subfigure illustrated the association results for chronic rhinosinusitis. The x-axis shows the localization of the gene and SNPs on build 36. The y-axis shows the p values on a log scale. The lower and upper dash lines represent p value thresholds of 0.05 and 0.0012, respectively. The gene structure for CYSLTR2 was taken from Fukai et al. . The upper and lower parts of each subfigure are shown on the same scale.
