Background: Neuromyelitis optica (NMO) and multiple sclerosis (MS) are autoimmune diseases of the central nervous system with complex pathogeneses. NMO was once considered to be a severe variant of MS. There has been more evidence that a non-synonymous exchange (rs763361/Gly307Ser) in the gene for CD226 is linked to several autoimmune diseases including multiple sclerosis (MS). However, no studies have investigated the role of rs763361 in the pathogenesis of NMO. Objectives: The goal of our study is to evaluate the role of CD226 Gly307Ser in neuromyelitis optica (NMO) in Southern Han Chinese. Methods: Eight-nine NMO patients, 93 relapsing-remitting multiple sclerosis (RRMS) patients, and 122 controls (CTLs) were enrolled. The rs763361 alleles of the subjects were determined by sequencing-based typing. Results: The results strongly support that the TT genotypes are associated with NMO but are not significantly correlated with susceptibility for MS. Conclusions: CD226 Gly307Ser may correlate with risk of NMO in Southern Han Chinese.

    ABSTRACT: Objectives: To identify the association of aquaporin-4 (AQP4) promoter polymorphism with the presence of anti-aquaporin-4 antibody (AQP4-Ab) in Southern Han Chinese patients with idiopathic demyelinating disorders of central nervous system. Methods: Eighteen neuromyelitis optica (NMO), thirty-eight conventional MS (CMS), thirteen recurrent myelitis (RM), six recurrent optic neuritis (RON) patients and thirty-nine matched controls were enrolled. Polymorphisms of AQP4 promoters 0 and 1 were determined by sequencing-based typing. Results: Fourteen polymorphism loci were observed in AQP4-promoter 0, while the six ones were observed in AQP4-promoter 1. Among them, the frequency of polymorphism at position -1003bp (A-G) of AQP4-promoter 0 in AQP4-Ab-positive patients was significantly higher than that in AQP4-Ab-negative patients and controls (former: 13/18 vs 20/45, P=0.046; latter: 13/18 vs 10/39, P=.001). The frequency of polymorphism at position between -401bp and -400bp (C inserted) of AQP4-promoter 1 in AQP4-Ab-positive and -negative patients was significantly higher than that in controls (former: 5/16 vs 0/28, P=0.008; latter: 8/38 vs 0/28, P=0.027). Conclusions: Polymorphism at position -1003bp (A-G) of AQP4-promoter 0 is associated with the presence of anti-AQP4 antibody. Genetic variation in AQP4 may account for the susceptibility to AQP4-Ab-positive NMO and NMO spectrum disorders in Southern Han Chinese population.

    ABSTRACT: The genetic traits that result in autoimmune diseases represent complicating factors in explicating the molecular and cellular elements of autoimmune responses and how these responses can be overcome or manipulated. This article focuses on the major non-major histocompatibility complex genes that have been found to be linked to autoimmune diseases. A given gene may associate with a number of autoimmune diseases and, conversely, a given disease may link to a number of common autoimmune disease (AD) genes. Collaboration and interaction among genes and the number of diseases that develop and the extensive risk factors shared among ADs further complicate the outcome. This article describes the various relationships between gene regions associated with multiple ADs and the complexity of those relationships.

    ABSTRACT: Multiple sclerosis (MS) pathogenesis results from both genetic and environmental factors. Genome-wide association studies (GWAS) have contributed considerably to our understanding of MS susceptibility through identification of genetic variants influencing risk and quantitation of their effect sizes. Immunologically relevant genes, including genes in the major histocompatibility complex region, are the primary genetic contributors to MS susceptibility. MS prevalence differs according to population, and most GWAS carried out to date have used datasets from people of European descent. Interpretation and application of GWAS results from Europeans to other populations require a good understanding of the genetic characteristics of each population, such as linkage disequilibrium patterns. The heterogeneity in global MS prevalence is partially explained by differences in risk allele frequencies in populations, which are due to the effects of migration, adaptation to new environments and genetic heterogeneity. Genetic studies of different populations can be expected to narrow down the putative causative regions and improve our understanding of MS pathogenesis. The literature record of genetic studies of neuromyelitis optica is much shorter than that of MS. Genes associated with neuromyelitis optica have been reported in the major histocompatibility complex region, as well as at other genetic loci, but only the susceptibility associated with the HLA-DPB1*05:01 and HLA-DRB1*03 alleles, and the association of a CYP7A single nucleotide polymorphism have been replicated. Here, we describe important genetic studies of MS and neuromyelitis optica in Europeans, African Americans, and Asians, and discuss the implications for disease incidence and future directions for genetic research.
