Background: Nicotinamide nucleotide transhydrogenase (NNT) gene mutations have been recently shown to cause familial glucocorticoid deficiency (FGD), by decreasing reactive oxygen species (ROS) detoxification in adrenocortical cells. Affected infants present within the first few months with isolated glucocorticoid deficiency.Objective and Hypotheses: To study the genetic etiology of four cases presenting uniquely with neonatal addisonian crisis (both min...

Background: Mutations in the gene HSD17B3 encoding the 17-beta hydroxysteroid dehydrogenase 3 enzyme cause testosterone insufficiency leading to XY DSD. In this study the clinical characteristics and molecular etiology of 3 new severe XY DSD cases from consanguineous families are elucidated.Clinical report: Three female patients (2 sisters and a single unrelated female) presented at ages 0.1, 8 and 0.7 years with ambiguo...
