The genetic variation in the CD14 rs2569190 promoter region contributes to the susceptibility of developing periodontitis. Since, CD14 gene polymorphism studies among various ethnic populations have produced conflicting results, the present study was designed to unearth the association between the CD14 rs2569190 gene polymorphism and generalized chronic periodontitis (GCP) in a South Indian population of Tamil ethnicity. Polymorphisms in the CD14 rs2569190 promoter region were analyzed in 96 subjects who were periodontally healthy and 96 patients with GCP. DNA extracted from peripheral venous blood was genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis. One-way analysis of variance, Chi-square testing, and logistic regression analysis were used to test association between GCP and the CD14 rs2569190 single nucleotide polymorphism (SNP). The distribution of the CD14 rs2569190 genotypes and allele frequencies showed significant differences between the test and control groups. Prevalence of the polymorphic TT genotype and T allele of the CD14 rs2569190 were significantly increased in GCP patients when compared with healthy controls. The results of the present study suggest that the T allele and the TT genotype of the rs2569190 SNP in the promoter region of the CD14 gene are associated with GCP in a South Indian population of Tamil ethnicity.
