Abstract

Multiple sclerosis (MS) and neuromyelitis optica (NMO) are chronic demyelinating diseases of the central nervous system (CNS). Recently, variants of vitamin D metabolizing genes, including rs12368653, rs10876994, rs118204009 and rs703842 in CYP27B1, and rs2248359 in CYP24A1 have been identified to be associated with the pathogenicity of MS in Caucasian populations. However, these results have not been replicated in Han Chinese population. Here we investigated the association of these variants with MS and NMO susceptibility in 149 MS patients, 110 NMO patients and 294 healthy controls using MassARRAY system and Sanger sequencing. We found that the frequencies of the A allele of rs703842 were higher in MS patients than controls (p=0.032), and statistical differences were observed in the genotypes of both rs703842 (p=0.013) and rs10876994 (p=0.001) between NMO patients and controls. In addition, we found difference in the genotype of rs12368653 between MS patients and controls (p=0.008). However, no difference was found in rs2248359 among these three groups. The reported rare mutation p.R389H (rs118204009) was not found in our study. In conclusion, our study suggested that variants of CYP27B1 were associated with both MS and NMO patients in Han Chinese population.
