DC, CC, and BC analysis indicated that ALB (serum albumin), PPARγ (peroxisome proliferator-activated receptor gamma), MAPK3 (mitogen-activated protein kinase 3), EGF (epidermal growth factor), and PTGS2 (prostaglandin G/H synthase 2) are closely related to pharyngitis. The gene discussed is MAP4K3; the disease is pharyngitis.
