The gene complex located on chromosome 19q13.4 encodes the Killer-cell Immunoglobulin-like Receptors (KIRs), which exhibit remarkable polymorphism in both gene content and sequences. Further, the repertoire of KIR genes varies within and between populations, creating a diverse pool of KIR genotypes. This study was carried out to characterize KIR genotypes and haplotypes among 379 Arab Kuwaiti individuals including 60 subjects from 20 trio families, 49 hematopoietic cell transplantation (HCT) recipients and 270 healthy Kuwaiti volunteer HCT donors. KIR Genotyping was performed

One nucleotide substitution in codon 85 of HLA‐DPA1*01:03:01:04 results in a novel allele HLA‐DPA1*01:03:34.

One nucleotide substitution in codon 179 of HLA‐DRB4*01:03:01:01 results in a novel allele HLA‐DRB4*01:152.
