Analysis of Pregnancy-Associated Plasma Protein-A and Interleukin-6 Gene Polymorphisms in Patients With Periodontitis

A total of 226 systemically healthy subjects, consisted of 112 S3GBC periodontitis patients (P group) and 114 periodontally healthy individuals (H group) were included in our study. Clinical and demographic data were recorded. Genomic deoxyribonucleic acid (DNA) molecules were obtained from peripheral blood. Genotype for IL-6 rs1800795 and PAPP-A rs7020782 polymorphisms were determined using real-time polymerase chain reaction with allele-specific probes. The genotypic or allelic distributions of PAPP-A and IL-6 gene polymorphisms were similar between groups (p\>0.05). Our finding suggests that there is no relationship between PAPP-A and IL-6 gene polymorphismS and S3GBC periodontitis, furthermore no difference was detected between periodontitis patients and healthy individuals regarding this gene polymorphism.
