Background: Interleukin 17F (IL-17F) is a pro-inflammatory cytokine that is recently proved to have a crucial role
in the emergence of autoimmune diseases; it induces the expression of various cytokines, chemokines and adhesion
molecules. IL-17F polymorphism is subsequently related to enhanced IL-17F expression and activity; which may
result in susceptibility to many autoimmune diseases including primary immune thrombocytopenia (PIT).
Aim of the study: This case- control study aimed to investigate the possible association between IL-17F gene single
nucleotide polymorphism (SNP) at rs 7488A/G and PIT susceptibility in Egyptian pediatric patients. Subjects
and Methods: A total of 50 children with PIT with mean age of 7 years, together with 50 age and sex matched
healthy controls were enrolled in the study for evaluation. Polymerase chain reaction- restriction fragment length
polymorphism (PCR-RFLP) was used for detection of IL-17F polymorphism at rs7488A/G.
Results: Regarding the genotypes distribution, the frequencies of the AA, AG and GG genotypes were 96, 2, and 2%
in PIT patients and 90, 10 and 0% in the control group respectively. The A and G allele frequencies were 97 and 3%
in the patients group versus 95 and 5% in the control group. There was no significant difference in either genotypes
or allelic distribution between PIT patients and the controls.
Conclusion: our study suggests that IL17F gene polymorphism at rs7488A/G may not contribute to the susceptibility
in development of primary immune thrombocytopenia in the Egyptian children.
