Abstract

CONTEXT: Adrenocortical adenomas (ACAs) are among the most frequent human neoplasias. Genetic alterations affecting the cAMP/protein kinase A signaling pathway are common in cortisol-producing ACAs, whereas activating mutations in the gene encoding β-catenin (CTNNB1) have been reported in a subset of both benign and malignant adrenocortical tumors. However, the molecular pathogenesis of most ACAs is still largely unclear. OBJECTIVE: The aim of the study was to define the genetic landscape of sporadic unilateral ACAs. DESIGN AND SETTING: Next-generation whole-exome sequencing was performed on fresh-frozen tumor samples and corresponding normal tissue samples. PATIENTS: Ninety-nine patients with ACAs (74 cortisol-producing and 25 endocrine inactive) negative for p.Leu206Arg PRKACA mutation. MAIN OUTCOME MEASURES: Identification of known and/or new genetic alterations potentially involved in adrenocortical tumorigenesis and autonomous hormone secretion, genotype-phenotype correlation. RESULTS: A total of 706 somatic protein-altering mutations were detected in 88 of 99 tumors (median, six per tumor). We identified several mutations in genes of the cAMP/protein kinase A pathway, including three novel mutations in PRKACA, associated with female sex and Cushing's syndrome. We also found genetic alterations in different genes involved in the Wnt/β-catenin pathway, associated with larger tumors and endocrine inactivity, and notably, in many genes of the Ca(2+)-signaling pathway. Finally, by comparison of our genetic data with those available in the literature, we describe a comprehensive genetic landscape of unilateral ACAs. CONCLUSIONS: This study provides the largest sequencing effort on ACAs to date. We thereby identified somatic alterations affecting known and novel pathways potentially involved in adrenal tumorigenesis.

  • Somatic activating mutations of GNAS occur in 5% to 17% of cortisol-secreting adrenal adenomas.

    “Somatic activating mutations of GNAS, which encodes the α-subunit of the stimulatory G protein (GSα), occur in 5% to 17% of adrenal adenomas which are cortisol secreting (142,143).”

  • PRKACA mutations may be associated with smaller adenomas but higher levels of cortisol production than adenomas without the mutation.

    “Mutations in PRKACA may be associated with smaller adenomas but higher levels of cortisol production than adenomas where this mutation is not present (143,148).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
