Title: Association of a NOS3 gene polymorphism with Behçet's disease but not with Vogt-Koyanagi-Harada syndrome in Han Chinese. Author: Zhou Y, Yu H, Hou S, Fang J, Qin J, Yuan G, Kijlstra A, Yang P. Journal: Mol Vis; 2016; 22():311-8. PubMed ID: 27114698. Abstract: PURPOSE: Previous studies have identified that nitric oxide synthase (NOS) genes are associated with several immune-mediated diseases. This study aimed to investigate whether NOS2 and NOS3 gene polymorphisms are associated with Behçet's disease (BD) and Vogt-Koyanagi-Harada (VKH) syndrome in a Han Chinese population. METHODS: An association analysis of NOS2/rs4795067, NOS3/rs1799983 and NOS3/rs1800779 was performed in 733 patients with BD, 800 patients with VKH syndrome, and 1,359 controls using PCR restriction fragment length polymorphism (PCR-RFLP) assay. Statistical analysis was performed with the chi-square test followed by the Bonferroni correction. RESULTS: The result showed a decreased frequency of the NOS3/rs1799983 GG genotype and an increased frequency of NOS3/rs1799983 GT genotype in the patients with BD (Bonferroni correction test [Pc]=0.02, odds ratio [OR]=0.74; Pc=2.1×10(-3), OR=1.57, respectively). No significant association was found between rs1799983 and VKH syndrome. NOS2/ rs4795067 and NOS3/rs1800779 were not associated with either BD or VKH syndrome. CONCLUSIONS: Our findings suggest that a NOS3/rs1799983polymorphism is associated with susceptibility to BD in Han Chinese.[Abstract] [Full Text] [Related] [New Search]
