Lack of Association Between the VEGFA Gene Rs699947 Polymorphism and Periodontal Disease.

PURPOSE:Periodontal disease is a chronic inflammatory disease characterised by the infiltration of inflammatory cells as well as activation of pathological angiogenesis in gingival tissues. Vascular endothelial growth factor (VEGF) plays a statistically significant role in the regulation of angiogenesis and induction of an inflammatory response in periodontal tissues. MATERIALS AND METHODS:We examined the association between the VEGFA gene rs699947 polymorphism and periodontal disease. This study enrolled 200 patients with periodontal disease (130 non-smokers and 70 smokers) and 160 control subjects (126 non-smokers and 34 smokers). RESULTS:There were no statistically significant differences in the distribution of VEGFA rs699947 genotypes and alleles between patients with periodontal disease and control subjects, also in the case when the analysis was performed in subgroups stratified according to smoking status. CONCLUSION:The results of this study suggest there is no association between the VEGFA gene rs699947 polymorphism and periodontal disease.
