Abstract

Primary aldosteronism is the most prevalent form of secondary hypertension. To explore molecular mechanisms of autonomous aldosterone secretion, we performed exome sequencing of aldosterone-producing adenomas (APAs). We identified somatic hotspot mutations in the ATP1A1 (encoding an Na(+)/K(+) ATPase α subunit) and ATP2B3 (encoding a Ca(2+) ATPase) genes in three and two of the nine APAs, respectively. These ATPases are expressed in adrenal cells and control sodium, potassium and calcium ion homeostasis. Functional in vitro studies of ATP1A1 mutants showed loss of pump activity and strongly reduced affinity for potassium. Electrophysiological ex vivo studies on primary adrenal adenoma cells provided further evidence for inappropriate depolarization of cells with ATPase alterations. In a collection of 308 APAs, we found 16 (5.2%) somatic mutations in ATP1A1 and 5 (1.6%) in ATP2B3. Mutation-positive cases showed male dominance, increased plasma aldosterone concentrations and lower potassium concentrations compared with mutation-negative cases. In summary, dominant somatic alterations in two members of the ATPase gene family result in autonomous aldosterone secretion.

  • In aldosterone-producing adenomas without KCNJ5 mutations, ATP1A1 abnormalities were found in 5.2% and ATP2B3 abnormalities in 1.6%, and these mutations were associated with increased plasma aldosterone concentrations and lower potassium concentrations than cases without the mutation.

    “In aldosterone-producing adenomas that did not have KCNJ5 mutations, abnormalities in ATP1A1 (encoding a Na+/K+ ATPase α subunit) were found in 5.2% and of ATP2B3 (encoding a Ca2+ ATPase) in 1.6%, with these mutations associated with increased plasma aldosterone concentrations and lower potassium concentrations than cases without the mutation (156).”

    From Adrenal incidentaloma (2020) · cites this paper as [156]

  • Somatic driver mutations in KCNJ5, ATP1A1, ATP2B3, CACNA1D, and CTNNB1 have been discovered in aldosterone-producing adenoma tissue, altogether accounting for most cases.

    “Similarly, somatic driver mutations in KCNJ5, ATP1A1, ATP2B3, CACNA1D, and CTNNB1 have been discovered in APA tissue, altogether accounting for most cases (157, 158, 161–164).”

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.
