Background: HSD3B2 is a rare cause of autosomal recessive primary adrenal insufficiency, potentially associated with under virilisation of XY males and virilisation of XX females. We present a case of a male infant presenting at term with ambiguous genitalia (DSD) with underlying diagnosis confirmed biochemically and genetically with a novel mutation of HSD3beta2.Objective: Case report.Patients and methods: Baby was born as FTND wi...

Background: Secondary pseudohypoaldosteronism (PHA) type 1 is an uncommon salt losing condition of infancy caused by transient resistance of the mineralocorticoid receptors (MR) of the renal tubule to aldosterone. This can be secondary to urinary tract infection (UTI), urinary tract malformation (UTM) or obstructive uropathy. Ninety percent of reported cases present before 3 months and nearly all are under 7 months of age.Objective and hypotheses: The co...

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...
