<p><b>New page</b></p><div>[[Hartnup disease]] is a [[hereditary]] nutritional disorder resulting in niacin deficiency. It is named after an English family with a genetic disorder that resulted in a failure to absorb the essential amino acid [[tryptophan]], tryptophan being a precursor for niacin synthesis. The symptoms are similar to pellagra, including red, scaly rash and sensitivity to sunlight. Oral niacin or niacinamide is given as a treatment for this condition in doses ranging from 50 to 100&nbsp;mg twice a day, with a good prognosis if identified and treated early. Niacin synthesis is also deficient in [[carcinoid syndrome]], because of metabolic diversion of its [[precursor (chemistry)|precursor]] [[tryptophan]] to form [[serotonin]].</div>FuzzyBot
