Protease, serine, 8 (PRSS8) is a gene that encodes a protein that functions as a trypsinogen - member of the trypsin family of serine proteases. The protein activates epithelial sodium channel (ENaC) via cleavage of the gamma subunits. Missense mutations, nonsense mutations, silent mutations, frameshift deletions, and in-frame insertions are observed in cancers such as endometrial cancer, intestinal cancer, and skin cancer.

PRSS8 is altered in 1.21% of all cancers with lung adenocarcinoma, colon adenocarcinoma, breast invasive ductal carcinoma, melanoma, and melanoma of unknown primary having the greatest prevalence of alterations [3].
