Background: Sporadic aldosterone-producing adenomas (APA) are relevant cause of endocrine related hypertension in Primary Aldosteronism (PA). Next generation sequencing techniques have identified somatic mutations in APA harbored in KCNJ5, ATP1A1, ATP2B3, CACNA1D, CTNNB1 and PRKACA genes. Yet, a number of APA harbor no mutations in candidate genes (designated as wild type, WT) and little is known about genotype/phenotype correlation.Objectives: We invest...

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 ...
