Primary aldosteronism caused by aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia is the most prevalent cause of secondary hypertension. Somatic mutations of KCNJ5, ATP1A1, CACNA1D and ATP2B3 have been shown to be involved in the formation of APA. We studied the immunoexpressions of CYP11B2 and HSD3B2, the rate-limiting enzyme for aldosterone production and the prevalent isoform of β-HSD found in APA respectively, and...

Aldosterone-producing adenomas (APAs) are the most frequent cause of primary aldosteronism (PA). Somatic mutations of KCNJ5, ATP1A1, CACNA1D and ATP2B3 are involved in APAs formation while CTNNB1 and GNAS somatic mutations have been described in both APAs and in cortisol-producing adenomas (CPAs). In contrast, mutations of PRKACA coding for the catalytic subunit of protein kinase A have been yet only identified in ...
