When samples obtained at the time of pneumonitis were compared with 12-week samples from controls, we observed higher titers of multiple IgG and IgM auto-reactive antibodies, with the strongest associations observed for IgG antibodies to CA125 (p= 0.001; FDR=0.03), CMV EXT (P= 0.01, FDR=0.13), and Angiotensin II type 1 receptor (p=0.01, FDR=0.16), and IgM fraction for ACHRG (p=0.00018, FDR=0.12), NSE (p=0.004, FDR=0.12), and BAFF (p=0.004, FDR=0.12) Figure 2A (full list provided in Supplementary Tables 4, 5). The gene discussed is ENO2; the disease is pneumonitis.
