Abstract

Although the main pathomechanism of multiple sclerosis (MS) is not known, an autoimmune response is presumed to involve its evolution and propagation. In this study, we examined how the kinesin light-chain 1 (KLC1) G56836C (rs8702) single nucleotide polymorphism (SNP) in intron 13 affects the occurrence of MS. This genetic variant was found to be associated with cognitive disturbances and neurodegeneration, and it was presumed to affect the kinesin function. Kinesin serves as a main cytoskeleton motor protein by carrying mitochondria and the molecular apparatus of myelin basic protein synthesis. The present association analysis of this genetic variant was performed in 102 relapsing-remitting MS patients and in 207 neuroimaging alteration-free controls. The KLC1 56836CC variant proved to exert a significant protective effect on the occurrence of MS (2.0% vs. 9.7%, P < 0.02; crude OR: 0.19, 95% CI: 0.04-0.82, P < 0.05; adjusted OR: 0.21, 95% CI: 0.018-0.88, P < 0.05). Our results draw attention to possible roles of the cytoskeleton in MS.
