Abstract

Context: Somatic gene mutations have been identified in only about half of cortisolproducing adenomas (CPAs). Affected genes include PRKACA, GNAS, PRKAR1A, and CTNNB1. Objective: This work aims to expand our understanding of the prevalence of somatic mutations in CPAs from patients with overt Cushing syndrome (OCS) and “subclinical” mild autonomous cortisol excess (MACE), with an immunohistochemistry (IHC)‒guided targeted amplicon sequencing approach using formalin-fixed paraffin-embedded (FFPE) tissue Methods: We analyzed FFPE adrenal tissue from 77 patients (n = 12 men, 65 women) with either OCS (n = 32) or MACE (n = 45). Using IHC for 17α-hydroxylase/17,20-lyase (CYP17A1) and 3β-hydroxysteroid dehydrogenase (HSD3B2), we identified 78 CPAs (32 OCS CPAs and 46 MACE CPAs). Genomic DNA was isolated from the FFPE CPAs and subjected to targeted amplicon sequencing for identification of somatic mutations. Results: Somatic mutations were identified in 71.8% (56/78) of the CPAs. While PRKACA was the most frequently mutated gene in OCS CPAs (14/32, 43.8%), somatic genetic aberrations in CTNNB1 occurred in 56.5% (26/46) of the MACE CPAs. Most GNAS mutations were observed in MACE CPAs (5/7, 71.4%). No mutations were observed in PRKAR1A. In addition to the known mutations, we identified one previously unreported mutation in PRKACA. Two patients with MACE harbored 2 adjacent tumors within the same adrenal gland - one patient had 2 CPAs, and the other patient had a CPA and an aldosterone-producing adenoma (identified by IHC for aldosterone synthase). Conclusion: A comprehensive FFPE IHC-guided gene-targeted sequencing approach identified somatic mutations in 71.8% of the CPAs. OCS CPAs demonstrated a distinct mutation profile compared to MACE CPAs. [ABSTRACT FROM AUTHOR]
