In colon cancer, we observed the simultaneous low expressions of chloride channel accessory 1 (CLCA1), UDP‐GlcNAc:betaGal beta‐1,3‐N‐acetylglucosaminyltransferase 6 (B3GNT6) and UDP glucuronosyltransferase family 2 member A3 (UGT2A3), which indicated an favourable prognosis. The gene discussed is UGT2A3; the disease is malignant colon neoplasm.
