Top claims

  • ▪Experiments showed that removing CDC42 from cells halts the hyperactive pyrin clump formation and inflammation driven by classical familial Mediterranean fever mutations.
  • ▪The CDC42 T43I mutation reshapes a surface hairpin loop on CDC42, causing it to bind abnormally tightly to the tail end of the pyrin protein.
  • ▪The MEFV functional atlas provides clinical utility by converting hundreds of previously uninterpretable genetic variants of uncertain significance into clear diagnostic answers.
