  1. Genes in the ALT_5'UTR set exhibit 5'UTR transcript diversity (AS and ATI), whereas, genes in the nonALT control set do not. Total number of genes in each set (top tier). Average 5'UTR length (nts) for transcripts in each set (middle tier). Total number of genes that contain uORFs (percentage in parenthesis), and average uORF lengths (nts) in alternative (ALT) and constitutive (CONSTIT) regions (bottom tier).
