We used the cBioPortal database to generate OncoPrint to display the mutation patterns of KARS, CDKN2A, TP53, and SMAD4 and mRNA expression (set the z-score threshold to 1.2 to define mRNA High and mRNA Low) of DLAT in TCGA-PAAD samples. This evidence concerns the gene KARS1 and pancreatic adenocarcinoma.
