Individuals with the most frequent genotype, which comprised 27% of the individuals studied, are homozygous for the group A haplotype. The remaining 110 KIR genotypes found in this study are either group A and group B heterozygotes or group B homozygotes (who are indistinguishable from heterozygotes by genotype alone).
Individuals possessing the most prevalent genotype, accounting for 27% of those studied, are homozygous for the group A haplotype. The remaining 110 KIR genotypes identified in this study fall into two categories: group A and group B heterozygotes or group B homozygotes (which cannot be distinguished from heterozygotes solely based on genotype).
