[Relationship between interleukin-6 gene-572C/G polymorphism and chronic periodontitis]

Area of Science:

• Genetics
• Immunology
• Periodontology

Context:

• Chronic periodontitis is a prevalent inflammatory disease affecting the gums and supporting structures.
• Interleukin-6 (IL-6) is a key cytokine involved in inflammatory processes.
• Genetic variations may influence an individual's susceptibility to chronic periodontitis.

Purpose:

• To investigate the association between the interleukin-6 (IL-6) gene -572C/G polymorphism and the risk of developing chronic periodontitis.
• To determine if specific genotypes or alleles of the IL-6 gene are more common in individuals with chronic periodontitis.

Summary:

• This study examined the IL-6-572C/G genotype polymorphism in 93 chronic periodontitis patients and 96 controls using PCR-RFLP.
• Results showed a significantly higher frequency of the -572GG genotype and G allele in chronic periodontitis patients compared to controls.
• The -572CG + GG genotype was associated with an increased odds ratio (1.88) for chronic periodontitis.

Impact:

• The IL-6-572C/G polymorphism, particularly the CG + GG genotype, may serve as a genetic susceptibility factor for chronic periodontitis.
• Findings contribute to understanding the genetic basis of chronic periodontitis in the Chinese Han population.
• This research may inform future genetic screening and personalized prevention strategies for periodontitis.
