An Association Study of rs2829803 Polymorphism in miRNA-155 with Multiple Sclerosis in Patients Referred to Farshchian Hospital of Hamadan City, (Iran)

Multiple sclerosis is a chronic autoimmune disease with inflammation of the myelin sheath of the central nervous system. A series of factors, such as environmental factors and polymorphisms have been known to be associated with it. In this study, the correlation between polymorphism of rs2829803 in miR-155 and multiple sclerosis, was investigated in the patients referred to Farshchian Hospital of Hamadan City.
In this case-control study, 130 patients (29% male, 71% female) with multiple sclerosis (age range, 17-69 years) and 150 healthy subjects (38% male, 62% female) (age range, 19-63 years), were selected as the control group. Genotyping was performed by Tetra-ARMS-PCR method.
A significant difference was observed in the genotypic distribution of miR-155 rs2829803 in dominant form (OR: 0.33, 95% CI: 1.19-0.58) (p=0.0001) and heterozygote (OR: 1.92, 95% CI:1.17-3.16) (p=0.01) in patients compared to the healthy subjects.
In line with previous studies on the relationship between miR-155 polymorphism (rs2829803) and multiple sclerosis disease, the results of this study confirmed the association of this polymorphism with increased risk of developing the disease.
