Coming back to Titin gene, are all exons equally important? GERP scores could tell us something about how the exons vary in conservation level at base-pair resolution.
In the above figure, the y-axis is the exon rank and the x-axis has boxplots of GERP scores for each exon. Exons with mean GERP scores above 0 are colored red and those below zero are colored blue. One can clearly see the GERP score reduce considerably between exons 160 and 200.
