A cohort of 225 Portuguese patients with sporadic pituitary macroadenomas diagnosed before the age of 40 years was studied by whole exome sequencing (WES) followed by the analysis of a virtual panel of 29 genes that have been associated with predisposition to pituitary adenomas.

The accuracy rate of ⁶⁸Ga-pentixafor PET/CT in identifying the dominant side of aldosterone secretion was not inferior to that of AVS.</div></div>","PeriodicalId":46328,"journal":{"name":"Journal of Clinical and Translational Endocrinology","volume":"39 ","pages":"Article 100384"},"PeriodicalIF":4.2,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143183414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
