Expanding genetic spectrum and discriminatory role of steroid profiling by LC‐MS/MS in 11β‐hydroxylase deficiency

Abstract

This first Indian study describes 13 11βOHD patients, including four with the rarer non-classic variant. A total of eight novel pathogenic variants were identified in our study, highlighting regional genetic heterogeneity. Measurement of ACTH-stimulated adrenal steroids by LC-MS/MS will help avoid the misdiagnosis of 11βOHD as 21OHD and has potential to distinguish classic from non-classic 11βOHD.
