This document discusses three types of congenital adrenal hyperplasia caused by deficiencies in the 11β-hydroxylase, 17α-hydroxylase, and 21-hydroxylase enzymes. Each enzyme deficiency results in different levels of mineralocorticoids, glucocorticoids, and androgens being produced, leading to distinct symptoms such as hypertension, low potassium, ambiguous genitalia, absent puberty, or salt wasting. The document provides a table comparing the effects of each enzyme deficiency.
