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.
The symptoms of isolated 17,20-lyase deficiency, in males, include pseudohermaphroditism (i.e., feminized, ambiguous, or mildly underdeveloped (e.g., micropenis, perineal hypospadias, and/or cryptorchidism (undescended testes)) external genitalia), female gender identity, and, in non-complete cases of deficiency where partial virilization occurs, gynecomastia up to Tanner stage V (due to low ...
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.
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 ...
For example, ADAM10 can cut off part of the HER2 receptor, thereby activating it. [5] ADAM genes are found in animals, choanoflagellates, fungi and some groups of green algae. Most green algae and all land plants likely lost ADAM proteins. [6] ADAMs are categorized under the EC 3.4.24.46 enzyme group, and in the MEROPS peptidase family M12B. [3]
Cytochrome b 5 deficiency is a rare condition and form of isolated 17,20-lyase deficiency caused by deficiency in cytochrome b 5, ...
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]
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.
