Abstract
Programmed cell death 1 (PD-1) is an immune checkpoint and has been reported to be associated with several autoimmune diseases. We aimed to investigate the association between human PD-1 gene (PDCD1) polymorphisms and multiple sclerosis (MS). This case-control study was conducted on 229 MS patients and 246 healthy controls. Genotyping of rs36084323 (PD-1.1 G/A), rs11568821 (PD-1.3 G/A) and rs2227981 (PD-1.5 C/T) polymorphisms was performed by PCR-RFLP technique. The frequency difference of PD-1.1 genotypes and alleles (-536 G/A) between patients and healthy controls was not significant. Regarding PD-1.3, the AA + AG genotype was found to be relatively higher in the control group. Concerning PD-1.5 (+7785 C/T), the frequency of T allele carriers (TT + CT) was relatively higher in MS patients, which was marginally insignificant (p = .07). PD-1 gene polymorphisms may be associated with MS; however, accurate conclusions require further studies with a larger number of samples.
