RESUMEN
Objective The aim of this study was to inve-stigate the associations between genetic variants in interleukin (IL)-33 and susceptibility to gout.Methods The genetic distributions of rs3939286 were detected in 1 100 men with gout and 1 227 ethnically matched controls using Taqman allelic discrimination real-time polymerase chain reaction (PCR).Hardy-Weinberg was used to verify the representativeness of the samples.Differences in genetic distributions between groups were investigated using x2 tests.The genotypephenotype relationship among gout patients was tested by analysis of variance.Results The frequencies of AA,AG and GG genotypes were1,101 and 998 (0.1％,9.2％ and 90.7％) among gout patients,while they were 1 132 and 1 094 (0.1％,10.7％ and 89.2％) among the controls.There were no significant differences in genetic distributions of IL-33 rs3939286 polymorphism between gout patients and controls (P=0.478 by genotype,x2=1.46,P=0.309 by allele).Conclusion Our results have revealed that the rs3939286 variant in IL-33 gene may be not involved in the development of gout in male gout patients of Shandong.However,further studies in other ethnic groups are needed to confirm the results.
