Most aldosterone-producing adenomas (APAs) have gain-of-function somatic mutations of ion channels or transporters. However, their frequency in aldosterone-producing cell-clusters of normal adrenals could suggest the existence of co-driver mutations which influence the development or phenotype of APAs [1]. Gain-of-function mutations in both CTNNB1 and the G-protein coupled receptor GNA11 were found by whole exome sequencing in 3/10 APAs. Further sequencing of...
