In the initial study, the G allele of rs10774671</span> was a </span>significantly protective factor against TB (P = 0.006) and the genotype of GG differed significantly between TB patients and controls under the codominant model (P = 0.008) after Bonferroni correction.
Associations between OAS1 polymorphisms (rs2240190, rs1131454, 10,774,671 and 11,066,453) and TB risk were established based on distributions of allelic frequencies using different genetic models.
The SS risk allele of rs10774671 has been shown by others to be associated with reduced OAS1 enzymatic activity and ability to clear viral infections, as well as reduced responsiveness to IFN treatment.
In this study, we examined the association between single-nucleotide polymorphisms (SNPs) in 3 innate immunity genes [2'-5'oligoadenylate synthetase 1 (OAS1) rs10774671, interleukin 28B (IL28B) rs12979860, and low molecular mass polypeptide 7 (LMP-7) at codon 49] besides cytomegalovirus (CMV) coinfection and susceptibility to HCC in genotype 4 (GT4) chronically infected Egyptian patients.
Polymorphisms in the promoter region of CD209 gene (rs735239, rs4804803, rs2287886) and OAS1 (rs1131454 and rs10774671), OAS2 (rs15895 and rs1732778), and OAS3 (rs2285932 and rs2072136) genes were investigated in 100 patients with CHIKV infection and 101 healthy controls to find out the association of these polymorphisms with CHIKV infection.

The polymorphism at OAS1 exon 7 rs3741981 might be a potential genetic marker and can be useful in the assessment of liver fibrosis progression and disease outcome in HCV-infected patients.
Polymorphisms in the OAS1 (rs1131454 and rs10774671), OAS3 (rs2285932 and rs2072136) and OAS2 (rs15895 and rs1732778) genes were studied using PCR followed by restriction fragment length polymorphism methods in 109 patients hospitalized for dengue (DEN) and 105 healthy controls (HCs) who have no documented evidence of symptomatic dengue.

Moreover, individuals carrying the A allele in these SNPs exhibited an increased risk for chronic HCV infection (rs2660 and rs10774671: OR = 1.356 [1.051-1.749]; rs3741981: 1.363 [1.085-1.712]).
No association was found between rs10774671 and MS. As the two SNPs are in linkage disequilibrium in Europeans, the previously reported association between rs10774671 and MS susceptibility might be driven by rs11352835, possibly explaining the contrasting results previously observed for the splice-site polymorphism.
A case/control study for MS indicated that rs11352835</span> is associated with disease susceptibility (for an allelic model with the deleted allele predisposing to MS, OR 1.27, 95% CI 1.072-1.513, p = 0.010).
OAS1 rs2660 may be a prostate cancer susceptibility polymorphism, which is a significant observation, especially in a context of the OAS1-RNaseL pathway.

Genomic DNA samples from a control group (n = 140) and from a case group of patients with prostate cancer (n = 164) were used for genotyping SNPs rs2660, rs1131454, and rs34137742 in all samples.

The minor allele variants of three OAS1 SNPs (rs3741981/Ser162Gly, rs1051042/Thr361Arg, rs2660), located in a linkage disequilibrium block of functional importance, were significantly associated with an increase in rubella virus-specific IL-2/T(h)1 response (p <or = 0.024).
