Why are there fewer cases in the 'Top Mutated Cancer Genes in Selected Projects' bar graph on the Project List Page, than there are affected cases listed on each project page?

There are less cases displayed with mutations in the 'Top Mutated Cancer Genes in Selected Projects' on the Project List Page because there is a filter on cases that have mutations on 1) Genes in the Cancer Gene Census and 2) Mutations with consequence types of {missense_variant, frameshift_variant, start_lost, stop_lost, initiator_codon_variant, stop_gained}.
