Investigation of IL-10 Gene Expression and rs1554286 SNP in Behçet's Disease

Abstract

Objective: Behcet's disease (BD) is a chronic, recurrent and inflammatory disorder characterized by oral and genital aphthous ulcerations, uveitis, skin lesions and skin pathergy reaction. There are many genetic studies focused on determining BD etiology. In this study, we aimed to investigate IL-10 gene expression and rs1554286 single nucleotide polymorphism (SNP) which is located in IL-10 gene. Material and Method: In this study, the blood specimens of BD patients (n=45) and healthy controls (HC) (n=28) were collected for RNA and DNA extraction. We genotyped rs1554286 from the DNA samples (45 BD, 28 HC) using real time PCR. We identified the IL-10 gene expression levels from cDNA samples of patients with sufficient sample amounts (29 patients with BD and 23 HCs). Results: We compared the expression levels of IL-10 gene and also genotyping analysis, and no significant difference was observed between BD patients and HC. Conclusion: In our study, which compared IL-10 gene expression and SNP genotyping between Behcet patients and healthy controls, no difference was found between the two groups. Since this may have occurred due to the low number of samples in our study, studies with higher sample numbers are needed.
