Next, we carried out a comprehensive meta-analysis, including seven autoimmune diseases (T1D, SLE, GD, HT, RA, MS, and AAD), three SNPs of IFIH1 (rs1990760, rs3747517, and rs10930046), and three ethnicities (Caucasian, Asian, and African), to investigate whether IFIH1 polymorphisms were associated with AID susceptibility. The gene discussed is IFIH1; the disease is myeloid sarcoma.
