The sex steroid deficiency produces effects similar to 17α-hydroxylase deficiency. Severely affected genetic females (XX) are born with normal internal and external genitalia and there are no clues to abnormality until adolescence, when the androgenic and estrogenic signs (e.g., breasts and pubic hair) of puberty either fails to occur or is ...
A disintegrin and metalloprotease 17 (ADAM17), also called TACE (tumor necrosis factor-α-converting enzyme), is a 70-kDa enzyme that belongs to the ADAM protein family of disintegrins and metalloproteases, activated by substrate presentation.
ADAMs (short for a disintegrin and metalloproteinase) are a family of single-pass transmembrane and secreted metalloendopeptidases. [1] [2] All ADAMs are characterized by a particular domain organization featuring a pro-domain, a metalloprotease, a disintegrin, a cysteine-rich, an epidermal-growth factor like and a transmembrane domain, as well as a C-terminal cytoplasmic tail.

Late onset CAH was originally characterized in 1957 by French biochemist Jacques Decourt, [126] but the association with mild 21-hydroxylase deficiency called nonclassical 21-hydroxylase deficiency, which is characterized by diverse hyperandrogenic symptoms appearing postnatally in males and females, was first described in 1979 by Maria New. [127]
Hyper-IgD syndrome (Mevalonate kinase deficiency) CIAS1-related diseases: Muckle–Wells syndrome; Familial cold autoinflammatory syndrome, types 1, 2, 3, and 4; Neonatal onset multisystem inflammatory disease; NLRP1 deficiency; PAPA syndrome (pyogenic sterile arthritis, pyoderma gangrenosum, acne) ADAM17 deficiency; Blau syndrome
ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13)—also known as von Willebrand factor-cleaving protease (VWFCP)—is a zinc-containing metalloprotease enzyme that cleaves von Willebrand factor (vWf), a large protein involved in blood clotting.
Symptoms of severe forms of PORD include ambiguous genitalia in males and females, congenital adrenal hyperplasia, cortisol deficiency, and Antley–Bixler skeletal malformation syndrome (ABS), while symptoms of mild forms include polycystic ovary syndrome in women and hypogonadism in men. [3]
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 ...
