ABSTRACT:

Systemic sclerosis is a chronic systemic disease with unknown variety of etiology, and has clinical chronic protests often progressive. Gene PTPN22 R620W polymorphism has been identified as a risk factor in the scleroderma disease, especially the limited one. The aim of this project is studying the relationship between gene PTPN22 R620W polymorphism with scleroderma disease. This was a clinical trial conducted on 70 patients with scleroderma referred to Golestan Hospital, Ahvaz, Iran and 70 healthy subjects with no history of genetic disorders, particularly autoimmune diseases referred to Iran Blood Transfusion Organization as control group. Diagnosis is based on physical examination and confirmation of rheumatologist. Sampling is done through Non-probability sampling convenient sampling. The PTPN22 R620W polymorphism had no significant relationship in all scleroderma patients and control group (P-value: 0.76, OR: 0.61). In addition, the gene in patients with limited scleroderma, diffuse scleroderma patients, scleroderma +ACA, -ACA scleroderma patients was not significantly more than the control group. This study showed that the prevalence of the gene PTPN22 R620W polymorphism in patients with scleroderma and its subtypes is not more than the control group.
