N2 - Background: Neuromyelitis optica (Nmo) and multiple sclerosis (mS) are chronic neuro-inflammatory diseases believed to arise from complex interactions between environmental and genetic factors. Recently, single nucleotide polymorphisms (SNPs) in interleukin (IL)-2 and-7 receptor alpha genes have been identified as novel susceptibility alleles for mS in genome-wide association studies. However, similar research on Nmo is limited. We aimed to investigate the association of IL2RA SNPs rs2104286 and rs12722489 and IL7RA SNP rs6897932 with Southern Han Chinese Nmo and mS patients. Methods: Frequencies of the three SNPs were examined in Southern Han Chinese mS cases (n=78), Nmo cases (n=67) and controls (n=133) using sequencing-based typing. Results: The rs2104286G frequency in the IL2RA gene was significantly higher in Nmo patients than in controls (puncorr=0.013, pcorr=0.026, oR:1.942, 95%CI:1.146-3.291). Conclusion: The rs2104286 G allele in IL2RA is present at higher frequencies in Nmo patients than in healthy controls within a Southern Han Chinese population.
