Abstract
Objectives: To determine the allelic frequencies and effects of genotypic variations in cytokine gene polymorphisms in a Saudi Arabian population. Methods: This cross-sectional study involved 41 patients with Primary Sjögren’s syndrome (pSS) and 71 healthy controls between October 2018 and May 2019. Single nucleotide polymorphisms genotyping was performed using the SEQUENOM MassARRAY ® System, targeting nine polymorphisms in different cytokine genes. Chi-square tests were used to compare the patients and controls. Results: The interleukin-1 beta (IL-1β) rs1143627 CT (control, 52.7%; patients, 21.2%) and TT + CT ( p = 0.003; p =0.033) genotypes were less frequent in patients with pSS than in healthy controls. The C allele in rs10488631 in the interferon regulatory factor 5 (IRF5) gene and the A allele in rs12583006 in the B-cell activating factor (BAFF) gene were associated with an increased risk of pSS development in the patient group. Conclusion: The CT genotype at −31 (rs1143627) in the IL-1β gene was not associated with a high risk of pSS development in the Saudi population, in contrast to what has been verified in other ethnicities. However, the C allele in rs10488631 in IRF-5 and the A allele in rs12583006 in BAFF were associated.
