Abstract:
Background and objectives: Rheumatoid arthritis (RA) is an autoimmune disease with a complex genetic background. The protein tyrosine phosphatase non-receptor type ۲۲ (PTPN۲۲) is a lymphoid specific protein tyrosine phosphatase which is involved in negative regulation of T cell response. Several studies have assessed the association between PTPN۲۲ single nucleotide polymorphisms (SNPs) with RA susceptibility. Here, we aimed to assess the association of PTPN۲۲ (۱۸۵۸ C>T) variant with the susceptibility to RA in northeast of Iran.
Methods: A total of ۱۲۷ RA patients and ۱۱۹ age- and sex- matched healthy donors were enrolled. The polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) technique (PCR-RFLP) was applied to detect PTPN۲۲ (۱۸۵۸ C>T) SNP. SPSS ۲۲.۰ software was used to analyze data using relevant statistical tests.
Results: Comparison of allele and genotype frequencies of PTPN۲۲ (۱۸۵۸ C>T) SNP in RA patients and healthy donors revealed no significant association with RA susceptibility.
Conclusion: The present study suggests that the PTPN۲۲ (۱۸۵۸ C>T) genetic variants are not associated with RA susceptibility and disease activity. While this is the first report from northeast of Iran, further studies are needed to confirm these findings
