X-linked Congenital Adrenal Hypoplasia with a Novel NR0B1/DAX Gene Mutation.

ABSTRACT

Background: The etiology of primary adrenal insufficiency has implications for further management of the condition. Case characteristics A 5-year-old boy presented in adrenal crisis with glucocorticoid and mineralocorticoid deficiency. Observation Investigations confirmed primary adrenal insufficiency and ruled out the common etiologies. Genetic testing identified a novel NR0B1/DAX gene mutation. Message A genetic diagnosis in children with primary adrenal insufficiency is useful to provide genetic counselling.
