Background: The etiopathogenesis of juvenile systemic lupus erythematosus (JSLE), a complex and complicated illness, is unknown. Genetic, environmental, and dysregulated immune system responses are all thought to contribute to the disease’s etiology. Important immunological molecules that regulate different immune cells and are associated with autoimmune disorders are TNFSF4 and IKZF1. Thus, our purpose was to discover if TNFSF4 and IKZF1 mutations left the Egyptian population genetically predisposed to SLE. Methods: Using real-time polymerase chain reaction (RT-PCR), polymorphism analysis of the TNFSF4 rs1234315 C/T and IKZF1 rs11980379 C/T genes was performed on extracted DNA from JSLE patients and healthy controls. Results: TNFSF4 frequencies (rs1234315 T allele, CT, TT genotypes, dominant and recessive models) were substantially associated with a higher incidence of JSLE (p < 0.05) compared to healthy controls. Conversely, IKZF1 frequencies (rs11980379 T allele, TC, TT genotypes, and dominant model) significantly correlated with a lower incidence of JSLE. Furthermore, the TC + CC rs11980379 genotype was identified as significantly associated with lower kidney biopsy grades and a lower incidence of lupus nephritis. Conclusions: Our findings suggest that TNFSF4 and IKZF1 polymorphisms affect vulnerability to juvenile SLE.
