Distribution of cancer genes across primary sites and cancer donors. a Number of total cancer genes and proportion of known and candidate cancer genes across the 31 tumor primary sites analyzed in the 267 cancer-specific studies. The number of cancer donors followed by the number of cancer genes is given in brackets for each primary site. b Proportion of candidate cancer genes over all cancer genes across the 31 tumor primary sites. The dot size is proportional to the donor cohort size. c Total number of cancer genes and cancer donors across the 31 tumor primary sites. The color scale in (b) and (c) indicates the number of screens for each primary site
