Although congenital adrenal hyperplasia is part of the normal neonatal screening, results might not be available for 3 to 4 weeks Congenital Adrenal Hyperplasia (CAH) is an intersex variation that effects 1 in every 10,000 to 18,000 people. Those with this variation have adrenal glands (glands above the kidneys that produce horomones such as cortisol and aldosterone) that do not properly function in adrenal horomone production

Congenital adrenal hyperplasia (CAH) refers to any of several autosomal recessive diseases resulting from defects in steps of the synthesis of cortisol from cholesterol by the adrenal glands Late onset congenital adrenal hyperplasia (LOCAH), also known as nonclassic congenital adrenal hyperplasia (NCCAH or NCAH), is a milder form of congenital adrenal hyperplasia (CAH), a group of autosomal recessive disorders characterized by impaired cortisol synthesis that leads to variable degrees of postnatal androgen excess Congenital adrenal hyperplasia consists of several disorders resulting from defective enzymes and proteins involved in steroid and cortisol synthesis pathways. Defects in steroid biosynthesis are caused by several genetic mutations and may lead to delayed puberty, precocious puberty or ambiguous genitalia in specific disorders

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency is a disorder of cortisol and aldosterone biosynthesis that results from mutations in the CYP21 gene encoding the adrenal 21-hydroxylase P-450c21.

Congenital adrenal hyperplasia. This inherited condition is characterized by abnormal production of steroid hormones, including cortisol and androgen, by your adrenal glands. Tumors. Rarely, an androgen-secreting tumor in the ovaries or adrenal glands can cause hirsutism. Medications. Some medications can cause hirsutism With congenital adrenal hyperplasia, congenital means present from birth, adrenals refer to the two adrenal glands that sit above the kidney, and hyperplasia refers to increased cell proliferation which leads to tissue growth.. So congenital adrenal hyperplasia is a disease where there are enlarged adrenal glands that are present at birth, and the reason for the adrenal enlargement is that. An XX fetus may have congenital adrenal hyperplasia, causing androgens which results in male development, and an XY fetus may have androgen insensitivity syndrome, causing female development.
