Differential analysis found 36 of 110 LLPS-related genes (RPL23A, UBC, NPM1, FBN1, APP,DDX3X, FYN, SUMO3, HNRNPA1, MYC, MAP1LC3B, XPO1, BRD4, ABL1,SPOP, KPNA2, TARDBP, FUS, NCK1, IPO5, EIF4EBP2, LBR, RARA, LCP2, DAZAP1, TNRC6B, HSPB2, TAF15, GATA2, GATA3, PIAS2, LAT, DYRK3, AR, CCNT1 and GRAP2) to be significantly differently expressed in RA patients (Figures 2A, B; Table 1), and the network between these LLPS-related genes is shown in Figure 2C. The gene discussed is GRAP2; the disease is rheumatoid arthritis.
