Relationship between GInLncSig and somatic mutation patterns in PAAD patients. Risk diagrams of training sets A, test sets C, and TCGA sets E, including lncRNA expression heat map, mutation distribution pattern, and UBQLN4 expression pattern. The expression levels of lncRNAs and UBQLN4 as well as somatic mutation levels changed with the increase in GInLncSig score. Somatic mutation counts and UBQLN4 expression level in the training set B, test set D and TCGA set F were significantly higher in the high-risk group than in the low-risk group
