Analysis of tumor necrosis factor-alpha, transforming growth factor-beta, interleukin-10, IL-6, and interferon-gamma gene polymorphisms in patients with chronic periodontitis.
BACKGROUND
Cytokine gene polymorphisms may have an impact on the susceptibility to and progression of chronic periodontitis. In this study, we analyzed the -1082 interleukin-10 (IL-10), -308 tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta 1 (TGF-beta1) (codons 10 and 25), -174IL-6, and +874 interferon-gamma (IFN-gamma) gene single-nucleotide polymorphisms in a cohort of patients with chronic periodontal disease.


METHODS
The diagnosis was made on the basis of standardized clinical and radiographic criteria. A total of 122 adult patients with chronic periodontitis and 114 unrelated, ethnically and age-matched white control subjects were genotyped by a polymerase chain reaction-sequence-specific primer.


RESULTS
The number of individuals carrying the -174IL-6 CC genotype was significantly higher in the group of patients than in the control group (odds ratio [OR] = 1.896; 95% confidence interval [CI] = 1.106 to 3.250; P = 0.0283). The TGF-beta1 (codon 25) GG (Arg(25)/Arg(25)) genotype was detected more frequently in control subjects than in periodontitis patients (OR = 0.459; 95% CI = 0.230 to 0.920; P = 0.0421).


CONCLUSIONS
The -174IL-6 and TGF-beta1 (codon 25) single-nucleotide polymorphisms are associated with susceptibility to chronic periodontitis in the population studied.
