Reference haplotype definitions. Haplotype numeric labels (Jiang et al. 2012) are shown with their definition via gene counts. Following Jiang et al. convention, some haplotypes (e.g., 7, 9) are distinguished by KIR2DS3/KIR2DS5 alleles instead of structural differences. In this study, some haplotypes (e.g., 1, 2) are combined, as KIR2DS4 full/deleted alleles are not considered in KPI’s genotyping.
