  1. The genotype combinations for the four tag SNPs able to identify each of the five DEFA1A3 haplotype classes. Due to the pattern of linkage disequilibrium (Additional file 1: Table S1), a diploid genotype profile can be used to determine the haplotype classes of the two haplotypes for the genotyped individual.
