Frequncey of PDCD1.3 gene polymorphisms in systemic lupus erythematosus patients

Background and Objective: Single Nucleotide Polymorphisms in programmed cell death which expressed at high level in T cells, plays an important role in the development and cause autoimmune disorders. This study was done to evaluate the frequncy of rs11568821 polymorphism in patients with systemic lupus erythematosus (SLE). Methods: This case-control study was done on 76 patients with SLE and 56 healthy controls. After DNA extraction, frequncy of polymorphisms PDCD1.3 by polymerase chain reaction and sequencing methods in subjects were determined. Results: There was a significant diference between frequency of allele and genotype at rs11568821 Polymorphism in region of intron 4 of PDCD1.3 gene in case and control groups (P<0.05). A allele and AG genotype was significantly higher in patients than healthy controls (9.5% vs 0.09%, P
