Clinical and Molecular Genetic Studies of Bilateral Adrenal Hyperplasias
Bibliographic record
Abstract
ACTH-independent, cortisol-producing hyperplasia is caused by 2 distinct disorders, primary pigmented nodular adrenocortical disease (PPNAD) and ACTH-independent macronodular adrenal hyperplasia (AIMAH). We will review recent findings on the clinical and molecular aspects of PPNAD and AIMAH. Inactivating mutations of PRKAR1A on 17q22-24, which codes for the type 1A regulatory subunit of protein kinase A, have been found in a subgroup of patients with PPNAD with and without Carney complex. AIMAH is a rare condition in which cortisol secretion may be mediated by non-ACTH circulating hormones such as gastric inhibiting polypeptide (leading to food-dependent Cushing's syndrome), vasopressin, catecholamines, luteinizing hormone, serotonin, angiotensin-II or leptin. The primary etiology of AIMAH remains unclear. Recently, we studied the expression profile of AIMAH by genomic cDNA microarray analysis. Several candidate genes were identified, suggesting pathways that affect the cell cycle, adhesion and transcription as possible mediators of adrenocortical hyperplasia.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
