Abstract
The mechanisms involved in the renin-independent regulation of aldosterone secretion in primary aldosteronism are poorly understood. In ACTH-independent Cushing's syndrome, cortisol secretion can be regulated by the aberrant expression of G-protein coupled receptors (GPCRs) in unilateral tumors and bilateral macronodular adrenal hyperplasia. By analogy, some recent studies identified overexpression or function of several GPCR as a potential cause for excess aldosterone production in some aldosteronomas and in bilateral idiopathic hyperaldosteronism. Initial studies have used in vitro techniques, while the clinical aldosterone responses were not assessed. More recently, several receptors have been shown to be expressed in aldosterone-producing adrenal tumors in vitro and to regulate aberrantly renin-independent aldosterone secretion in vivo. The prevalence of aberrant hormone receptors in primary aldosteronism could be elevated, but larger systematic studies are required to establish its true frequency. The identification of aberrant adrenal GPCRs by in vivo functional studies offers the potential for novel pharmacological therapies that either suppress the endogenous ligands or block the receptor with specific antagonists.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
