[citation needed] In women with mild cases, elevated blood pressure and/or infertility is the presenting clinical problem. 17α-hydroxylase deficiency in genetic males results in moderate to severe reduction of fetal testosterone production by adrenal glands and testes. Undervirilization is variable and sometimes complete.
ADAM17 is an 824-amino acid polypeptide.[5] [6]ADAM17 has multidomain structure that includes a pro-domain, a metallo-protease domain, a disintegrin domain, a cysteine-rich domain, an EGF-like domain, a transmembrane domain, and a cytoplasmic tail.
CAH due to 21-hydroxylase deficiency is the most common cause of ambiguous genitalia in genotypically normal female infants (46XX). Less severely affected females may present with early pubarche . Young women may present with symptoms of polycystic ovarian syndrome ( oligomenorrhea , polycystic ovaries, hirsutism ).
A study has revealed that serum progesterone concentrations in boys (10 days to 18 years old) with 21-hydroxylase deficiency reached levels up to 10.14 ng/mL, i.e. similar to female luteal values, while in the control group of boys, average level was 0.07 ng/mL (0.22 nmol/L), with values ranging from 0.05 to 0.40 ng/mL.

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 ...
Androgen deficiency most commonly affects women, and is also called Female androgen insufficiency syndrome (FAIS), although it can happen in both sexes. [ 2 ] [ 3 ] Androgenic activity is mediated by androgens (a class of steroid hormones with varying affinities for the androgen receptor ), and is dependent on various factors including androgen ...
17-β-Hydroxysteroid dehydrogenase III deficiency is a cause of 46,XY disorder of sex development (46,XY DSD) that presents in males with variable effects on genitalia which can be complete or predominantly female with a blind vaginal pouch. Testes are often found in the inguinal canal or in a bifid scrotum.
This is a list of primary immunodeficiencies (PID), which are immune deficiencies that are not secondary to another condition.. The International Union of Immunological Societies recognizes nine classes of primary immunodeficiencies, totaling approximately 430 conditions.
