In GSE49604 study we found DEAH (Asp-Glu-Ala-His) box polypeptide 32 gene (DHX32) levels to be strongly associated to FCGR2A gene expression, while in GSE1050 RA study we found regulator of G-protein signaling 12 gene (RGS12) to correlate significantly with FCGR2A levels (S1 Fig). The gene discussed is DHX32; the disease is rheumatoid arthritis.
