Fig. 1.
Linkage results across the genome for eight CD studies for the weighted analysis, showing −log10 (p value) against chromosomal location, with a single point plotted for each 30 cM bin. Thresholds for nominal, suggestive, and genome-wide significance are shown. Crossed points represent bins where SNPs with p < 10−4 were identified in the genome-wide association study [10]. p values from the hypergeometric distribution for specific linkage thresholds are indicated on the left.
