title: Single nucleotide polymorphisms of cytokine genes in the healthy Slovak population.
abstract: Cytokines are molecules that control and modulate the activities of numerous target cells via binding to specific receptors. The observed differences in the cytokine production among individuals can be, at least partially, explained by gene polymorphisms. Several cytokine gene polymorphisms have been identified to play a role in susceptibility to various diseases, including autoimmune, infectious, allergic or cardiovascular diseases. The aim of the current study was to determine allele and genotype frequencies of 22 polymorphisms in 13 cytokine genes in the healthy Slovak population and to compare them with data available from six populations from Central and Southern Europe. A polymerase chain reaction with sequence-specific primers was used to genotype polymorphisms within genes encoding IL-1alpha, IL-1beta, IL-1R, IL-1RA, IL-4Ralpha, IL-12, IFN-gamma, TGF-beta, TNF-alpha, IL-2, IL-4, IL-6 and IL-10 in a sample of 140 unrelated Slovak subjects. The allelic distribution of all polymorphisms in the Slovak population was very close to that in the geographically and historically closest populations in Central Europe--the Czech and the Polish. However, several differences were found between the Slovak and four populations from Southern Europe. The obtained data represent a basis for further studies on association of cytokine gene polymorphisms with some diseases.
