Allele 2 frequencies are from Caucasian controls. Within each group, genotypes (not shown) for each marker were in Hardy-Weinberg equilibrium. Moderate linkage disequilibrium was observed across this region.

^*Coding strand format, e.g., SNP1 T coding-common-1 allele, which means, for SNP1, the T allele is the common allele on the coding strand and is referred to as allele 1.
