congenital adrenal hyperplasia

congenital adrenal hyperplasia
(CAH) a group of inherited disorders in which deficiencies of enzymes that catalyze the biosynthesis of cortisol result in compensatory hypersecretion of corticotropin and subsequent adrenal hyperplasia as well as excessive androgen production. There are several different forms, numbered in order of increasing severity, of which the most common type is type III, or 21-hydroxylase deficiency (see accompanying table). They range from “classic” forms present at birth with severe salt wasting or hypertension and pseudohermaphroditism to less severe “nonclassic” forms of later onset. See also deficiency conditions at names of specific enzymes.
