Background: DAX-1 (NR0B1) plays a key role in adrenal and reproductive development. It interacts with other nuclear receptors; however, its exact biological role remains unclear. In men most patients with X-linked adrenal hypoplasia congenita (AHC) present with acute adrenal failure. To date DAX-1 mutations have been found in more than 100 families or patients with X-linked AHC.Results: We report the case of a 2.5-year-old boy who presented with a histor...

Background: Primary hypoaldosteronism (PA) is a rare inborn disorder with life-threatening symptoms in newborns and infants due to an aldosterone synthase defect. As plasma aldosterone concentration (PAC) can remain in the normal range, interpretation of the laboratory findings could be difficult and might lead to delayed initiation of therapy.Objective and Hypotheses: This study aims to show that PAC/PRC (plasma renin concentration) rat...
