It leads to impaired cortisol synthesis, resulting in increased adrenocorticotropic hormone stimulation and consequent accumulation of steroid precursors, which are diverted to androgen synthesis. In addition, the accumulation\nof 11-deoxycorticosterone, which is a potent mineralocorticoid, causes hyporeninemic hypokalemic hypertension. We report the clinical, hormonal, and genetic profiles of five children with 11\u03b2-OHD, emphasising phenotypic variability, a median 2-year diagnostic delay, the crucial role of hormonal profile in diagnosis, and management challenges, including post-treatment central\nprecocious puberty. Two novel CYP11B1 variants were identified in two unrelated patients. Hydrocortisone replacement resolved hypertension in only one of the three hypertensive patients; others required spironolactone. Early differentiation of 11\u03b2-OHD from 21-hydroxylase deficiency is critical to prevent hypertension-related morbidity.<\/jats:p>","DOI":"10.20945\/2359-4292-2026-0073","type":"journal-article","created":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T19:34:42Z","timestamp":1784576082000},"page":"1-7","source":"Crossref","is-referenced-by-count":0,"title":["Rare types of congenital adrenal hyperplasia: report of five children with 11\u03b2-hydroxylase deficiency including pathogenic and novel CYP11B1 variants"],"prefix":"10.20945","volume":"70","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2844-022X","authenticated-orcid":false,"given":"Anju","family":"Bala","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4191-3765","authenticated-orcid":false,"given":"Sayan","family":"Banerjee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7796-6665","authenticated-orcid":false,"given":"Arun","family":"George","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1840-5711","authenticated-orcid":false,"given":"Priyanka","family":"Srivastava","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-8415-7655","authenticated-orcid":false,"given":"Mohit","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-3391-2092","authenticated-orcid":false,"given":"Neha","family":"KC","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7026-3469","authenticated-orcid":false,"given":"Jaivinder","family":"Yadav","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0039-2142","authenticated-orcid":false,"given":"Rakesh","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3279-6002","authenticated-orcid":false,"given":"Devi","family":"Dayal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8510","published-online":{"date-parts":[[2026]]},"container-title":["Archives of Endocrinology and Metabolism"],"original-title":[],"link":[{"URL":"https:\/\/www.aem-sbem.com\/article\/rare-types-of-congenital-adrenal-hyperplasia-report-of-five-children-with-11%ce%b2-hydroxylase-deficiency-including-pathogenic-and-novel-cyp11b1-variants\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T19:34:44Z","timestamp":1784576084000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.aem-sbem.com\/article\/rare-types-of-congenital-adrenal-hyperplasia-report-of-five-children-with-11%ce%b2-hydroxylase-deficiency-including-pathogenic-and-novel-cyp11b1-variants\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.20945\/2359-4292-2026-0073","relation":{},"ISSN":["2359-3997","2359-3997"],"issn-type":[{"value":"2359-3997","type":"print"},{"value":"2359-3997","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
