Gene alteration frequencies by cohort

477 cohorts mapped to this entity or its descendants. Each frequency is affected / profiled within one cohort; cohorts are shown separately because case selection, sequencing depth and definitions differ. By default the cohort with the most cases profiled is shown.

#	Gene	Alteration	Affected (n)	Profiled (n)	Frequency (%)	Source

Cohorts mapped to a descendant (e.g. a subtype) are included because their cases belong to this entity by definition; the mapping and its match type are shown per cohort.
