<h2>Crohn's disease data</h2>

<h3>Description</h3>


<p>The data set consist of 103 common (&gt;5% minor allele frequency) SNPs 
genotyped in 129 trios from an European-derived population. These 
SNPs are in a 500-kb region on human chromosome 5q31 implicated as 
containing a genetic risk factor for Crohn disease.
