Neuromyelitis optica (NMO) is a serious inflammatory demyelinating disease (IDD), characterized by the inflammation and demyelination of optic nerves and spinal cords, which subsequently leads to the loss of function. In a previous genome-wide association study, cluster of differentiation 58 (CD58) region was found to be susceptible for the risk of multiple sclerosis (MS) in Caucasian, and the association between CD58 variants and MS was replicated in Americans. However, no study has been conducted to explore the possible association between CD58 and NMO yet. Thus, this study aimed to investigate the association of CD58 polymorphisms with the risk of NMO in a Korean population.


Using TaqMan assay, 6 single nucleotide polymorphisms (SNPs) were genotyped in 98 NMO patients and 237 normal controls (N = 336). Logistic regression analysis was conducted to find a possible association between CD58 polymorphisms and NMO.


The analysis results showed that 6 variations (rs2300747, rs1335532, rs12044852, rs1016140, CD58_ht1, and CD58_ht3) showed significant associations (P = 0.002 ~ 0.008, Pcorr = 0.01 ~ 0.04).


The genetic variations in CD58 may be associated with the susceptibility of NMO in a Korean population. Based on previous studies, we suspect that the A allele of rs2300747 may decrease CD58 RNA expression, thus increasing NMO risk. Also, we deduced that the G allele of rs1016140 caused an increase of T cell activity, which in turn eased the access of AQP4 antibody into central nervous system (CNS) and ultimately leading to NMO development.
