Abstract
The IRF5 (interferon regulatory factor 5) gene encoding a transcription factor is involved in the regulation of interferon synthesis and other proinflammatory cytokines. It is assumed that the IRF5 gene is associated with juvenileonset systemic lupus erythematosus (jSLE), a chronic autoimmune disease that develops in childhood and differs from the adult subtype of SLE in a number of its manifestations. The aim of the presented work was to conduct a pilot study of IRF5 rs2004640 polymorphism in the population of children in Belarus and its association with the development of jSLE. Genotyping of DNA samples was performed using real-time PCR in a group of patients diagnosed with
jSLE (38 people) and in the clinical control group without autoimmune and inflammatory diseases (378 people). The frequency of the IRF5 rs2004640 minor T allele was determined in the Belarusian population of children (under the age of 17). It was found that the rs2004640 TT genotype is associated with the risk of the jSLE development (OR = 2.27; 95% CI 1.08–4.76; p = 0.035) that after further investigations may improve an early diagnosis of jSLE.
