Association of genetic variations of interleukin-6 polymorphism (rs1800795) with susceptibility to Hashimoto’s thyroiditis in West Algerian population
Aim: Hashimoto’s thyroiditis is a polygenic auto-immune disease with a complex etiopathogenesis. It is more common in females. An imbalance between pro-inflammatory and anti-inflammatory cytokines may play an important role in the disease pathogenesis. Numerous studies have been conducted to find an...

| description | Aim: Hashimoto’s thyroiditis is a polygenic auto-immune disease with a complex etiopathogenesis. It is more common in females. An imbalance between pro-inflammatory and anti-inflammatory cytokines may play an important role in the disease pathogenesis. Numerous studies have been conducted to find an association between genetic polymorphisms and the development of Hashimoto’s thyroiditis. In this context, we proposed to study the impact of the interleukin-6 (IL-6) gene polymorphism (rs1800795) on the genetic susceptibility to Hashimoto’s thyroiditis.
Methods: Polymorphism in IL-6 gene (rs1800795) was assessed in a case-control study involving a population of Western Algeria with 81 Hashimoto’s thyroiditis patients and 211 unrelated healthy subjects, matched in age and sex. The DNA was extracted by a magnetic bead-based technique. The genetic study was performed by molecular biology: real-time PCR using TaqMan single nucleotide polymorphism (SNP) genotyping assay with Applied Biosystems 7500 device.
Results: Results showed that the GG and GC genotypic distribution is similar between patient and control groups with a higher frequency of the GG genotype (80.25% in patients and 78.67% in controls vs. 19.75% of patients and 20.38% of controls with the GC genotype). The CC genotype is absent in patients and present in only 02/211 healthy subjects. The frequency of the polymorphic G allele was similar in the two groups, with 90.1% and 88.8% in patients and controls respectively (P > 0.05).
Conclusions: This study reports no significant difference in IL-6 (-174 G/C) gene polymorphism at the allelic or the genotypic level between Hashimoto’s patients and the control group (P > 0.05). No association between the SNP IL-6 rs1800795 and susceptibility to Hashimoto’s thyroiditis in Western Algerian population. |
