Evaluation of the Frequency of Osteopontin Gene Polymorphism (rs28357094 T>G) and its Receptor Gene (ITGA4- rs1449263 A>G) in Multiple Sclerosis Patients in Comparison to Healthy Controls in Isfahan, Iran, Population

Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS). Various factors including genetic and environmental factors are involved in the prevalence of MS. The Osteopontin (OPN) and its receptor Integrins alpha-4/beta-1 (ITGA4) have important role in immune response, so their encoding gene could be considered as a candidate for susceptibility to MS diseases. In the present study, we evaluated the frequency of OPN (rs28357094T > G) and ITGA4 (rs1449263A>G) polymorphisms in MS patients compared with healthy controls in Isfahan, Iran population.
Blood samples were collected from 100 patients with multiple sclerosis and 100 healthy controls. After DNA extraction, OPN (rs28357094) and ITGA4(rs1449263) polymorphisms were detected with high resolution melt real time polymerase chain reaction (HRM Real Time PCR) technique. The results were analyzed with the SPSS software.
Findings: In this study, frequency of TT genotype (OPN-rs28357094) (P = 0.020, OR = 1.85) and AA genotype (ITGA4 - rs1449263) (P = 0.012, OR = 2.10) in Patients with multiple sclerosis were higher than the control group significantly.
The results of this study show that rs28357094 T>G on OPN gene and ITGA4-rs1449263A > G polymorphisms were associated with susceptibility to multiple sclerosis in Isfahan population.
