▶NOS2A, TLR4, and IFNGR1 interactions influence pulmonary tuberculosis susceptibility in African-AmericansAssociationN=766Velez DR et al.(2009)· Human Genetics
A case-control association study in African-Americans (279 cases, 166 controls) and Caucasians (198 cases, 123 controls) examined 39 SNPs in the NOS2A gene for pulmonary tuberculosis susceptibility. Ten NOS2A SNPs were associated with TB in African-Americans, with the strongest associations at rs2274894 (OR=1.84, 95% CI 1.23-2.77, p=0.003) and rs7215373 (OR=1.67, 95% CI 1.17-2.37, p=0.004). Strong gene-gene interactions were observed between NOS2A SNPs and variants in IFNGR1 and TLR4 genes, suggesting synergistic effects on TB susceptibility.

PhD thesis describing comprehensive genome-wide association studies of acute anterior uveitis (AAU) in European (2,752 cases, 3,836 controls) and East Asian (821 cases, 4,898 controls) populations. European descent GWAS identified HLA-B at genome-wide significance plus 11 suggestive loci (ERAP1, NOS2, MERTK). East Asian GWAS identified HLA-B and ERAP1 at genome-wide significance plus 12 suggestive loci (GPR68, RHBDD2). Mendelian randomization confirmed ERAP1 as functionally relevant and showed genetically predicted CRP levels positively associated with AAU risk.
About NOS2
Nitric oxide is a reactive free radical which acts as a biologic mediator in several processes, including neurotransmission and antimicrobial and antitumoral activities. This gene encodes a nitric oxide synthase which is expressed in liver and is inducible by a combination of lipopolysaccharide and certain cytokines. Three related pseudogenes are located within the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Jul 2008]
