Survival curves of the 4 core TMB-related genes. A-D. ALDH1A2, DUOXA2, and GALNT9 were negatively associated with survival rate, while IGLL1 was positively associated with survival rate. ALDH1A2, aldehyde dehydrogenase 1 family member A2; DUOXA2, dual oxidase maturation factor 2; GALNT9, polypeptide N-acetylgalactosaminyltransferase 9; IGLL1, immunoglobulin lambda like polypeptide 1.
