Prostaglandin-endoperoxide synthase 2 (prostaglandin G/H synthase and cyclooxygenase) (PTGS2) is a gene that encodes a protein that is the key enzyme in prostaglandin biosynthesis. Missense mutations, silent mutations, and nonsense mutations are observed in cancers such as skin cancer, colon cancer, and endometrial cancer.

PTGS2 is altered in 1.17% of all cancers with high grade ovarian serous adenocarcinoma, anaplastic astrocytoma, bladder urothelial carcinoma, cervical mucinous adenocarcinoma, gastric type, and colon adenocarcinoma having the greatest prevalence of alterations [3].
