Although IFIH1, RSAD2, and PARP9 were found to be associated with a variety of autoimmune or inflammatory disease development, such as SLE, RA, Sjögren’s syndrome (SS), type 1 diabetes (T1D), and AITD (Frommer and Kahaly, 2021; Zedan et al., 2021), we did not find that these genes were differentially expressed between the recurrent GD group and the normal group. This evidence concerns the gene RSAD2 and Sjogren syndrome.
