The laboratory findings of MIS-A include pancytopenia, elevated cardiac markers including troponin and brain natriuretic peptide (BNP), increased inflammatory markers, hypoalbuminemia, hypertriglyceridemia, and high liver enzymes [6-8]. MIS-A is also characterized by an overexuberant inflammatory response, as indicated by a substantial increase of inflammatory markers of CRP, ESR, ferritin, and procalcitonin and elevated coagulopathy markers. The gene discussed is ESR1; the disease is blood coagulation disease.
