Differentially expressed genes were validated by digital molecular barcoding technology. The fold change (FC) for each gene was greater than 2. Transcript levels for the TAC1, PREX2, ITGBL1, TMOD1, and NALCN genes were higher in adult samples (black bars), while transcript levels for the HIST1H3A, HISTH4E, HSPA2, and CAPN6 genes were higher in pediatric samples (white bars).
