Killer cell immunoglobulin-like receptors (KIR) are encoded by polymorphic genes and have as binding human leukocyte antigen (HLA) class I molecules. The aim of this study was to investigate the distribution of KIR genes and inhibitory KIR/HLA pairs in a population from Southern Brazil, in the state of Paraná, and to compare the results with results from other populations. The genotyping of 16 KIR genes and HLA class I alleles of 289 unrelated individuals was accomplished by reverse sequence-specific oligonucleotide Luminex (One Lambda, Inc., Canoga Park, CA). This Brazilian population demonstrated several similarities to Caucasian populations with regard to the frequency of KIR genes. Thirty-eight genotypes were defined in which the most frequent was the homozygous haplotype A (33.2%). Therefore, it was possible to define two new genotypes. Most of the individuals demonstrated at least one inhibitory KIR/HLA pair. Two pairs were the most frequent (40.4%), followed by three pairs (38.2%), one pair (14.6%), and four pairs (6.4%). The KIR2DL2/3 + HLA-C1 pair was the most frequent (79.9%) and the least frequent pair was KIR3DL2 + HLA-A3/11 (25.0%). This study demonstrated the diversity of KIR genes in a population of Paraná, as well as the characteristic pattern of Caucasians with racial admixture, which enabled the definition of two new genotypes and the identification of one individual without the inhibitory KIR/HLA pair.
