Distribution of killer cell immunoglobulin-like receptor genes in population of Vojvodina, Serbia

Background: Killer cell immunoglobulin-like receptors (KIRs) are glycoproteins regulating the response of natural killer (NK) cells and a few sub-sets of T-cells. The KIR gene frequencies and genotype content vary considerably among different ethnic groups. Aim: The aim of this study was to analyse...

Description
Summary:Background: Killer cell immunoglobulin-like receptors (KIRs) are glycoproteins regulating the response of natural killer (NK) cells and a few sub-sets of T-cells. The KIR gene frequencies and genotype content vary considerably among different ethnic groups. Aim: The aim of this study was to analyse KIR gene polymorphism in the population of Vojvodina and to compare it with selected worldwide populations. Subjects and methods: The studied sample consists of 134 healthy unrelated individuals, residents of different geographical regions of Vojvodina. DNA samples isolated from peripheral blood leukocytes by the silica-based extraction method were used in reverse PCR-SSO and PCR-SSP technique to detect the presence and absence of KIR genes. Results: All 16 KIR genes, a total of 37 different KIR genotypes, were observed in the Vojvodina population with the presence of framework and pseudogenes in all individuals. The neighbour-joining phylogenetic tree shows that the Vojvodina population is in the same cluster with Croatians, Turkish, Russians, Czechs, Irish, Italians, French, Macedonians and Polish. The Vojvodina population shows polymorphism of the KIR gene family present in other European and European-derived populations studied previously. Conclusion: The present study may serve as a reference for comparisons in further anthropological and disease association studies and also provide more informative data valuable for donor search strategy in haematopoietic stem cell transplantation.
