Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by impaired cortisol synthesis. [ 1 ] [ 2 ] It results from the deficiency of one of the five enzymes required for the synthesis of cortisol in the adrenal cortex . [ 3 ]

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), [1] a group of autosomal recessive disorders characterized by impaired cortisol synthesis that leads to variable degrees of postnatal androgen excess. [1] [2] [3] [4]
Differential diagnosis of Adrenocorticotropic hormone deficiency includes Congenital adrenal hyperplasia, Addison's disease, and Secondary adrenal insufficiency. [ 1 ] Plasma ACTH levels when off glucocorticoid replacement therapy are the best parameter for differential diagnosis, as levels in primary adrenal insufficiency are generally above ...
The type of issue you have and the degree to which it affects your body's hormone levels determine the symptoms. [2] The adrenal gland produces hormones that affects growth, development and stress, and also helps to regulate kidney function. There are two parts of the adrenal glands, the adrenal cortex and the adrenal medulla.
It accounts for less than 5% of the cases of congenital adrenal hyperplasia and is inherited in an autosomal recessive manner with a reported incidence of about 1 in 1,000,000 births. [2] The most common forms of this condition impair both the 17α-hydroxylase activity and the 17,20-lyase activity of CYP17A1.
Other causes include Congenital adrenal hyperplasia, insulin resistance, hyperprolactinemia, Cushing's disease, certain types of cancers, and certain medications. [4] [1] [3] Diagnosis often involves blood tests for testosterone, 17-hydroxyprogesterone, and prolactin, as well as a pelvic ultrasound. [1] [4] Treatment depends on the underlying ...
Congenital adrenal hyperplasia due to 11β-hydroxylase deficiency is a form of congenital adrenal hyperplasia (CAH) which produces a higher than normal amount of androgen, [1] resulting from a defect in the gene encoding the enzyme steroid 11β-hydroxylase (11β-OH) which mediates the final step of cortisol synthesis in the adrenal. 11β-OH CAH results in hypertension due to excessive ...
