Hartnup Disease

Hartnup disease is a rare hereditary disease associated with impaired absorption of the amino acid tryptophan in the intestine. As a result, a person experiences a number of symptoms:

  1. Mental retardation
  2. Thickening and roughness of the skin, especially exposed to sunlight
  3. Impaired coordination of movements and gait

Clinically, Hartnup's disease resembles pellagra, since both diseases are associated with tryptophan deficiency. The main treatment method is taking medications containing nicotinamide. A diet high in protein is also recommended.

Hartnup disease is a rare genetic disease. It is transmitted in an autosomal recessive manner. Timely diagnosis and adequate therapy allow achieving good results in treatment and improving the quality of life of patients.



Hartnup's disease or tripperagonal mental dystrophy is a genetically determined condition that is accompanied by rapid intellectual and mental decline. And also the presence of specific tryptic acidotic toxicosis in patients

This disease affects a small number of people. Scientists have discovered it in 278 people on the planet; on the list, the disease is one hundred and ninth most common.

It manifests itself in slow mental development for an average of four to six years.

All the bodies of sufferers are covered with a characteristic “potbelliness” (the so-called intense pigmentation of the skin). Cafe-au-lait spots form on the torso, neck, and arms, which can spread to the face and arms. In the area of ​​redness, significant differences in skin color are observed. The disease also causes significant deterioration in cognitive abilities and delayed development. Patients often suffer from disorders



Hartn's disease (also known as Hartnup Disease or Transallergic Cellular Acrasia) is a rare genetic disorder characterized by impaired absorption of the amino acid tryptaphan. As a result of this defect, patients experience various symptoms, including mental retardation, rough skin, changes in muscle tone, and others. The disease is named in
