Table 3 Percentages of pair-wise interactions that were significant (P < 0.05), classified by the gene(s) in which the interacting SNPs lie. Gene combinations in which there are substantially more significant interactions than the 5% expected by chance are indicated in bold. The counts that contribute to each percentage are also shown in parentheses as a fraction. The presence of "-" in the table indicates that no pairs of SNPs in this gene are 0.5 cM apart.
