Background: Primary Aldosteronism (PA) is the commonest curable cause of hypertension. Whole exome sequencing (WES) of an aldosterone producing adenoma from a 46-year-old man with resistant hypertension revealed a novel somatic mutation (Val380Asp) of the single transmembrane domain of Cell Adhesion Molecule-1 (CADM1). A Gly379Asp mutation was identified by WES of a PA patient in Munich. Both patients were cured of hypertension by adrenalectomy.Method: A...

Background: PA is the commonest curable cause of hypertension. Whole exome sequencing (WES) in 2011 and 2013 identified common somatic mutations in genes regulating membrane polarisation in 60-80% of aldosterone-producing adenomas (APA). In search of the missing variants, we undertook further WES. One APA from a 46-year-old gentleman revealed a novel somatic mutation (Val380Asp); which introduced a charged amino-acid into the single transmembrane domain of Cell Adhesion Molecu...
