Background: Patients with NNT (Nicotinamide Nucleotide Transhydrogenase) gene mutations, a rare cause of glucocorticoid and mineralocorticoid deficiency. Adrenal Rest Tumor (ART) in females, reported so far only in noncompliant patients with congenital adrenal hyperplasia and elevated ACTH levels, is very rare (<20 cases world-wide). This study characterizes the pathophysiology, the molecular ontogeny and methylation analysis of a unique ART in a female wit...

Introduction: Patients homozygous for mutation in the PCSK-1 gene present clinically with severe congenital diarrhea and variable hormonal defects due to lack of enzyme/prohormone processing by Prohormone Convertase 1/3 (PC1/3). Although absence of spontaneous puberty has been reported in patients with PCSK-1 mutations, no peptide hormone(s) in the hypothalamus-pituitary-gonadal axis (HPG) have been reported to be dependent on PC1/3 cleavage. Here we studied t...
