GlossaryNon-Classical Adrenal Hyperplasia

partial enzyme deficiency causing excess androgen production

Non-Classical Adrenal Hyperplasia (NCAH) is a milder form of congenital adrenal hyperplasia that typically presents later in life, often during adolescence or adulthood. It is caused by a partial deficiency in the enzyme 21-hydroxylase, leading to an overproduction of androgens (male hormones). Symptoms can include irregular menstrual cycles, excessive hair growth (hirsutism), and acne in females, while males may experience early signs of puberty.
