Single nucleotide polymorphisms (SNPs) within the first intron of CD58 have been independently confirmed to be related to the risk of MS. We here provide evidence that these SNPs may implicate an altered processing of an intronic microRNA.
In general, results from the current study indicate that CD226 and HLA-G, but not CD58 genetic polymorphisms are associated with increased risk of MS in Isfahan population similar to European populations.
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.
Recent association studies in multiple sclerosis (MS) have identified and replicated several single nucleotide polymorphism (SNP) susceptibility loci including CLEC16A, IL2RA, IL7R, RPL5, CD58, CD40 and chromosome 12q13-14 in addition to the well established allele HLA-DR15.
We observed a trend for association of rs3135388 (HLA-DRB1*1501, p < 0.01), rs7090530 (IL2RA, p < 0.026) and rs1841770 (ZIC1, p < 0.017) with a younger age at MS onset and of rs12044852 (CD58, p < 0.035) with shorter time to reach EDSS6.
We also replicated several known MS associations (HLA-DR15, P = 7.0 x 10(-184); CD58, P = 9.6 x 10(-8); EVI5-RPL5, P = 2.5 x 10(-6); IL2RA, P = 7.4 x 10(-6); CLEC16A, P = 1.1 x 10(-4); IL7R, P = 1.3 x 10(-3); TYK2, P = 3.5 x 10(-3)) and observed a statistical interaction between SNPs in EVI5-RPL5 and HLA-DR15 (P = 0.001).

To determine whether novel risk loci associated with systemic lupus erythematosus or multiple sclerosis may confer susceptibility to SSc, we tested single-nucleotide polymorphisms (SNP) from ITGAM, ITGAX, and CD58 for associations.
Minor (C) variant of the single-nucleotide polymorphism (SNP) rs1335532 is associated with lower MS risk according to genome-wide association studies (GWAS) and its presence correlates with higher CD58 mRNA levels in MS patients.
Of the 17 IMSGC SNPs, five SNPs showed genome-wide significant association with MS: HLA-DRA (P=8E-124), IL7R (P=6E-09), IL2RA (P=1E-11), CD58 (P=4E-09) and CLEC16A (P=3E-12).
In addition, they imply that concentrations of susceptibility alleles at IL2RA, IL7R, EVI5, KIAA0350, and CD58 are partly responsible for the heightened prevalence of multiple sclerosis within multiplex families.
