Primary aldosteronism is the most common form of secondary hypertension. Somatic mutations in KCNJ5, ATP1A1, ATP2B3 and CACNA1D have been described in 50% of aldosterone producing adenomas (APA). To identify genetic alterations in new genes, we performed whole exome sequencing in 23 patients with APA negative for recurrent mutations in known driver genes. A low number of somatic variations were identified per patient, ranging from 1 to 22. N...

Recurrent somatic mutations in KCNJ5, CACNA1D, ATP1A1 and ATP2B3 have been identified in aldosterone producing adenoma (APA). Although the role of these mutations in regulating aldosterone biosynthesis has been clearly established, the mechanisms involved in proliferation and APA formation still remain to be elucidated. The aim of our study was to identify pathways involved in adrenal cortex nodulation and APA formation.Transcriptomic a...
