Figure 1. Association results for the five Crohn's disease sample sets.
Top panel shows SNPs, their positions in the genes and the linkage disequilibrium structure between them. SNP names in red were genotyped in the second phase of the study, subsequent to the sequencing experiment. Middle panel shows D′ in the upper left and r2 in the lower right. (a–e) Lower panels show results from association analysis of Leuven trios (a), Liège trios (b), Liège case-control cohort (c), Québec trios (d) and Toronto trios (e). P values for individual alleles are reported in a logarithmic scale on the y axis. Color spectrum represents strength of linkage disequilibrium and frequency of the associated alleles.
