Weng et al. [104] analyzed clinical data in patients suffering from Kawasaki disease with CAA and found reduced serum ANXA1 levels; serum ANXA1 levels were positively correlated with erythrocyte sedimentation rate (ESR), IL‐6, and D‐dimer (DD) levels, which may lead to the hypercoagulable state of Kawasaki disease. This evidence concerns the gene ANXA1 and thrombophilia.
