title: The Importance of VEGF-KDR Signaling Pathway Genes should Not Be Ignored When the Risk of Developing Multiple Sclerosis is Taken into Consideration.
abstract: Vascular endothelial growth factor (VEGF) and its receptor kinase insert domain-containing receptor (KDR) pathway trigger the process of angiogenesis as well as inflammation, which contributes to the development and progression of demyelinating lesions in multiple sclerosis. This work is a case-control study comprising of a total of 400 subjects with multiple sclerosis and 400 healthy controls. Participants were subjected to neurological examination and peripheral blood sampling for genotyping. Polymorphisms in the VEGF and KDR genes were assessed using the restriction fragment length polymorphism (RFLP-PCR) method. A significantly higher frequency of the T allele and TT genotype of the VEGF 936C > T (rs3025039) polymorphism was found in the multiple sclerosis group than in the healthy control group (P = 0.01 [OR = 1.41] and P = 0.01 [OR = 3.12], respectively). In addition, VEGF 936C  >  T showed an association with patients in a recessive model. However, the KDR -604T > C (rs2071559) polymorphism showed no significant difference in either allelic or genotype frequency between the two groups. Taken together, the results of the present study suggests that the T allele of the rs3025039 in VEGF gene could be considered a risk factor for developing multiple sclerosis in the Iranian population.
