Distribution of 22 cytokine gene polymorphisms in the healthy Czech population.

ABSTRACT

Cytokine gene polymorphisms (CGP) have been implicated in the pathogenesis of immune-mediated diseases including transplant complications via their effect on cytokine production and regulation. This study aimed to determine population frequencies of selected cytokine single nucleotide polymorphisms in the healthy Czech population and compare them with the data from other selected European populations. CGP were genotyped by polymerase chain reaction with sequence-specific primers (PCR-SSP) using the Heidelberg kit in 120 unrelated Czech healthy individuals. Chi-squared analysis was used to test for a deviation from Hardy-Weinberg equilibrium. Allelic and genotype frequencies and carriage rates were determined for 22 CGP located within 13 cytokine genes in total. The frequencies observed in this study were similar to those available from the other two geographically close Central European centres, but they differed for several CGP from the data reported in south European populations. The data on the distribution of 22 CGP in the healthy Czech population reported here may be utilized to investigate possible associations of CGP with diseases or transplantation outcome.
