What causes congenital adrenal hyperplasia (CAH)?

In normal pattern of sexual development, the adrenal gland and hormones function like this:

The adrenal glands and hormones:

  • Adrenal glands, which are located on the top of each kidney, are responsible for releasing three different types of steroid hormones:
    • glucocorticoids, which help modulate our sugar metabolism. The glucocorticoid involved in CAH is called cortisone.
    • mineralocorticoids, which modulate our fluids and electrolytes. The mineralocorticoid involved in CAH is called aldosterone.
    • sex steroid hormones, which aid in the formation of sex organs. The adrenal gland releases the male hormone androgen (testosterone) and the female hormone estrogen.
  • Normally, the adrenal gland secretes the hormones directly into the blood stream, in three equally prominent metabolic pathways. This balance allows for the normal production of androgen and estrogen.

Hormones and CAH

  • In CAH, an enzyme deficiency blocks the pathways to the glucocorticoid and mineralocorticoid, impairing the body’s ability to produce cortisol and aldosterone.
  • The overabundance of androgen leads to the virilization (masculinization) of a female fetus. This is responsible for the ambiguous genitalia in females born with this condition.
  • While masculinization of a male fetus is possible, it’s less noticeable.

10 common questions about congenital adrenal hyperplasia causes

1Can congenital adrenal hyperplasia go away?
The milder and more common form of CAH is called nonclassic. ... Although there is no cure, with proper treatment, most people with congenital adrenal hyperplasia can lead normal lives.
2What is congenital adrenal hyperplasia newborn?
Congenital adrenal hyperplasia is a genetic disorder. In children with CAH, the gene (21-hydroxylase) that makes the enzyme needed to produce cortisol and aldosterone is not working properly. In order for a child to be born with CAH, both parents must be carriers of the mutated gene and pass it on to their baby
3What is Classical Congenital Adrenal Hyperplasia?
Congenital Adrenal Hyperplasia (CAH) is a family of inherited disorders affecting the adrenal glands. The most common form is 21-hydroxylase deficiency (21-OHD), which is inherited in severe or mild forms. ... The milder form, called Non-classical CAH (NCAH), may cause symptoms at anytime from infancy through adulthood
4Can CAH be cured?
Right now, there is no cure for CAH, but there is treatment. Some people with mild CAH may not need to take medicine all the time
5Is CAH a disability?
Specific learning disabilities have been rarely reported in congenital adrenal hyperplasia. The impact of hormones on cognition is still not clearly defined, but it is postulated that females with this condition have excess prenatal androgen stimulation, which increases the risk for cognitive impairment
6What is female adrenal hyperplasia?
Congenital adrenal hyperplasia. Congenital adrenal hyperplasia is an inherited disorder that results in low levels of cortisol and high levels of male hormones, causing development of male characteristics in females, and early puberty in both boys and girls
7What happens if progesterone is too high?
High levels of progesterone are associated with the condition congenital adrenal hyperplasia. However, the high progesterone levels are a consequence of and not a cause of this condition. Also, high levels of progesterone are associated with an increased risk for developing breast cancer
8Does congenital adrenal hyperplasia cause infertility?
Fertility in patients with congenital adrenal hyperplasia. ... If intensifying glucocorticoid treatment does not lead to tumour decrease, surgical intervention may be considered, but the effect on fertility is not yet known. In females with CAH the degree of fertility depends on the phenotype of the CAH.
9Is adrenal hyperplasia cancerous?
Since the vast majority of these cancers make too much hormone (cortisol, testosterone, estrogen, aldosterone, etc.), this is an obvious place to start. Keep in mind, however, that most non-cancerous tumors of the adrenal glands (benign adenomas and hyperplasia) will also secrete too much hormones
10What is the difference between Addison's disease and congenital adrenal hyperplasia?
Primary adrenal insufficiency is due to impairment of the adrenal glands. 80% are due to an autoimmune disease called Addison's disease or autoimmune adrenalitis. One subtype is called idiopathic, meaning of unknown cause. Other cases are due to congenital adrenal hyperplasia or an adenoma (tumor) of the adrenal gland.
