Background: Biallelic mutations of the CYP11B2 aldosterone synthase gene cause deficiency of aldosterone synthesis. Patients exhibit isolated deficiency of aldosterone biosynthesis, increased plasma renin activity, increased steroid precursors desoxycorticosterone, corticosterone, as well as 18-hydroxy-desoxycorticosterone, and show salt wasting and poor growth. The aldosterone synthase enzyme has 18-hydroxylase (corticosterone methyloxidase type I, CMO I) and 18-oxidase (CMO ...

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...
