The data set consist of 103 common (>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.
The positions, names and haplotype blocks reported are as follows,
An example use of the data is with the following paper,
