Polymorphic Variants of Immune Response Genes as a Risk Factor for the Development of Primary Progressive Multiple Sclerosis

Objectives. To analyze the involvement of immune response genes in the pathogenesis of primary progressive multiple sclerosis (PPMS). Materials and methods. A representative cohort of 111 ethnically Russian patients with PPMS took part in a multicenter study. The involvement of immune system genes in the pathogenesis of PPMS was analyzed by investigating the associations of variants of cytokines genes and genes involved in antigen processing and presentation by antigen-presenting cells with the disease. Results and conclusions. Carriership of the IL4 genotype (rs2243250)*C/C and CLEC16A (rs6498169)*G/G was found to have a positive association with the development of PPMS in Russian patients. The association described in studies of other populations, HLA-DRB1*15 with a high risk of developing this form of MS, was confirmed.
