Background: Triple A syndrome is a rare autosomal recessive disorder characterized by adrenal failure, alacrima, achalasia, and a variety of neurological features. In 70% of the families it is caused by mutations in the AAAS gene. Linkage analyses indicated genetic heterogeneity and exome sequencing revealed two further genes causing triple A-like syndromes.Objective and hypotheses: To summarise the genotypes and phenotypes of classic triple A s...

21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in the CYP21A2 gene. 21OHD causes a wide array of clinical symptoms that result from gluco- and mineralocorticoid deficiency and adrenal androgen excess. In most cases, supra-physiological glucocorticoid doses are necessary which may cause short stature, obesity, hypertension, cardiovascular and metabolic co-morbidity with reduced quality of lif...
