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.
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.

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 ...
Brunner syndrome is caused by a monoamine oxidase A (MAOA) deficiency, which leads to an excess of monoamines in the brain, such as serotonin, dopamine, and norepinephrine (noradrenaline). In both mice and humans, a mutation was located on the eighth exon of the MAO-A gene, which created a dysfunctional MAO-A gene.
17β-Hydroxysteroid dehydrogenase III deficiency is a rare autosomal recessive disorder of sexual development condition that is a cause of 46,XY disorder of sex development (46,XY DSD). The impaired testosterone biosynthesis by 17β-hydroxysteroid dehydrogenase III (17β-HSD III), [ 6 ] [ 7 ] presents as atypical genitalia in affected males.
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
The enzyme adenosine deaminase is encoded by the ADA gene on chromosome 20. [1] ADA deficiency is inherited in an autosomal recessive manner. This means the defective gene responsible for the disorder is located on an autosome (chromosome 20 is an autosome), and two copies of the defective gene (one inherited from each parent) are required in order to be born with the disorder.
Treatment for all forms of this condition primarily relies on a low-protein diet, and depending on what variant of the disorder the individual suffers from, various dietary supplements. All variants respond to the levo isomer of carnitine as the improper breakdown of the affected substances results in sufferers developing a carnitine deficiency.
