Therefore, we evaluated the role of rs10774671 in regulating gene expression of OAS1 and OAS3 in peripheral blood mononuclear cells (PBMCs) from patients with SS (n = 54) and from healthy controls (n = 104) by RT-qPCR assays according to the methods in our previous studies35–38. This evidence concerns the gene OAS3 and synovial sarcoma.
