Hartnup disease is a hereditary nutritional disorder resulting in niacin deficiency.
2.
Hartnup disease is a genetic disorder that reduces tryptophan absorption, leading to pellagra.
3.
Hartnup disease is a deficiency of the tryptophan amino acid transporter, which results in pellagra.
4.
Elevated levels of tryptophan are also seen in Hartnup disease, a disorder of amino acid transport.
5.
It may also result from alterations in protein metabolism in disorders such as carcinoid syndrome or Hartnup disease.
6.
He also defined new amino-acid diseases such as various forms of Fanconi syndrome, Hartnup disease, argininosuccinic aciduria and homocystinuria.
7.
In Hartnup disease, urinary excretion of proline, hydroxyproline, and arginine remains unchanged, differentiating it from other causes of generalized aminoaciduria, such as Fanconi syndrome.
8.
Hartnup disease is a disorder of amino acid transport in the intestine and kidneys; otherwise, the intestine and kidneys function normally, and the effects of the disease occur mainly in the brain and skin.
9.
The neutral amino acid transporter " SLC6A19 " ( affecting glycine, proline, and other neutral amino acids like cysteine and tryptophan ), associated with Hartnup disease, plays a role in iminoglycinuria as a modifier to PAT2 mutations and is also directly affected by the actions of SIT1.
10.
"' Hartnup disease "'( also known as " pellagra-like dermatosis " and " Hartnup disorder " ) is an autosomal recessive metabolic disorder affecting the absorption of nonpolar amino acids ( particularly tryptophan that can be, in turn, converted into serotonin, melatonin, and niacin ).
