Objective: Primary aldosteronism (PA) is the first cause of endocrine hypertension accounting for about 6% of all cases of hypertension. According to international guidelines, PA screening is based on plasma aldosterone-to-renin concentration ratio (ARR) computation. Nevertheless, measurement of urine aldosterone excretion may be of interest since it integrates aldosterone secretion over 24 hours. However, available urine aldosterone immuno-assays have poor specificity.<p ...

Introduction: Primary aldosteronism (PA) is the most frequent form of secondary hypertension. Over the past 10 years, important discoveries have been made regarding the genetic basis of aldosterone producing adenoma and familial forms of primary aldosteronism. In most cases, genetic abnormalities are found in genes coding for ion channels (KCNJ5, CACNA1D, CACNA1H, CLCN2) and pumps (ATP1A1, ATP2B3). These mutations affect intracellular ion homeostasis and/or c...

Primary aldosteronism (PA) is the most frequent form of secondary hypertension and is due to autonomous aldosterone production by the adrenal gland. During the last decades, major advances have been made in our understanding of the disease with the identification of germline or somatic mutations in ion channels and pumps. These mutations enhance calcium signaling, the main trigger of aldosterone biosynthesis. The objective of our work was to elucidate, using chemogenetic tools...
