Also, Porritt et al. identified eight autoantigens in MIS-C that were previously seen as autoantigens in autoimmune diseases, including TROVE2 (SLE and Sjogren’s syndrome), KLHL12 (primary biliary cirrhosis and Sjogren’s syndrome), HK1 (primary biliary cirrhosis), ATP4A (type I diabetes and corpus atrophic gastritis), and FAM84A (inflammatory bowel disease) (Porritt et al., 2021). This evidence concerns the gene KLHL12 and Sjogren syndrome.
