Adrenogenital Syndrome

Synonyms

Congenital adrenal hyperplasia; 21‐hydroxylase deficiency

Definition

Congenital adrenal hyperplasia is a group of inborn errors of metabolism arising from enzyme defects in the biosynthesis pathways of adrenal corticosteroids, resulting in inadequate production of glucocorticoids and mineralocorticoids and excess production of adrenal androgens.

Pathology/Histopathology

The adrenal cortex produces three principle groups of corticosteroids: mineralocorticoids responsible for electrolyte balance, glucocorticoids necessary for carbohydrate mobilization and potentiation of catecholamine action in response to stress, and adrenal androgens necessary for growth and sexual development. Adrenal corticosteroid production begins with the uptake of serum cholesterol and transport into the mitochondrium of the cells of the adrenal cortex, under the stimulation of adrenocorticotropic hormone (ACTH), gonadotropins, and steroidogenic acute regulatory protein (StAR).
