The COVID-19 convalescents had significantly elevated immunoglobulins, Orosomucoid 2 (ORM2), peroxiredoxin-2 (PRDX2), hemoglobin subunits (HBD, HBB and HBA1), as well as proteins involved in cholesterol transport such as cholesteryl ester transfer protein (CETP) and apolipoprotein A1 (APOA1). The gene discussed is PRDX2; the disease is COVID-19.
