A20, encoded by TNFAIP3, is a negative-feedback inhibitor of NF-κB. Grey and colleagues identify natural human variants of TNFAIP3, which lower A20 activity and increase autoinflammatory responses. These alleles were inherited by descendants of Denisovans who crossed the Wallace Line to inhabit Oceania.
