Hi Katelyn,
The mutation count/frequency in the Mutated Genes table is not restricted to driver mutations. However certain mutation types are filtered out during the import process, including silent, intron, 3’utr/flank, 5’utr (some 5’flank mutations for promotor regions are allowed in).
Regarding deeper annotation, if you visit the patient view page, accessible via the “View selected cases” button on the study view page:
you can choose to display additional properties of each gene/mutation belonging to the patient:
