    Abstract:
    OBJECTIVE: Despite substantial research efforts worldwide, the role of inflammatory cytokine IL-1β in the onset of febrile seizures (FS) remains controversial. The aim of this study was to assess the relationship between rs16944 polymorphism of the IL-1β-511T gene and occurrence of simple FS in a sample of Han children in northern China. METHODS: The IL-1β-511T gene rs16944 was genotyped by SNaPshot SNP technique in 141 FS children and 130 healthy control subjects. The genotypic and allelic frequencies in the two groups were comparatively analyzed. RESULTS: There were no significant differences in genotypic and allelic frequencies of rs16944 polymorphism of the IL-1β-511T gene between FS patients and control subjects (P>0.05).When the clinical data on A/A, A/G and G/G genotypes of the rs16944 polymorphism in FS patients, there was statistically significant difference in age of first onset (χ(2)=19.491, P<0.01), temperature of first onset (χ(2)=9.317, P<0.05) and family history of FS (χ(2)=26.798, P<0.01). CONCLUSIONS: There is no association between rs16944 polymorphism of the IL-1β-511T gene and the incidence of FS in Han children in Northern China. However, the differences in genotypes of this polymorphism might be associated with pathogenesis and prognosis of simple FS in the population studied.
