Here we leveraged a large set of MIS-C patient samples (n=199) to identify a distinct set of host proteins that are differentially targeted by patient autoantibodies relative to matched controls. We identified an autoreactive epitope within SNX8, a protein expressed primarily in immune cells which regulates an antiviral pathway associated with MIS-C pathogenesis. In parallel, we also probed the SARS-CoV-2 proteome-wide MIS-C patient antibody response and found it to be differentially reactive to a distinct domain of the SARS-CoV-2 nucleocapsid (N) protein relative to controls. This viral N region and the mapped SNX8 epitope bear remarkable biochemical similarity. Furthermore, we find that many children with anti-SNX8 autoantibodies also have T-cells cross-reactive to both SNX8 and this distinct domain of the SARS-CoV-2 N protein. Together, these findings suggest that MIS-C patients develop a distinct immune response against the SARS-CoV-2 N protein that is associated with cross reactivity to the self-protein SNX8, demonstrating a link from the infection to the inflammatory syndrome.
