NIH Rare Diseases:47 Hartnup disease is a metabolic disorder characterized by abnormal transport of certain amino acids in the kidney and gastrointestinal system. It is a type of aminoaciduria. The condition may be diagnosed based on the results of newborn screening tests. Most people with the condition have no symptoms (asymptomatic). For those who do show symptoms, the onset of the disease is usually between the ages of 3 and 9; occasionally the disease may present in adulthood. Mental development is usually normal, though a few cases with intellectual impairment have been reported. The signs and symptoms of Hartnup disease incude skin photosensitivity, neurologic findings, psychiatric symptoms, and ocular (eye) findings. Hartnup disease is caused by mutations in the SLC6A19 gene and is inherited in an autosomal recessive manner. People with Hartnup disease may benefit from a high-protein diet, protection from sunlight, vitamin supplementation, and avoidance of certain drugs/medications. In some cases, treatment with nicotinamide supplements and tryptophan ethyl ester may be indicated. Last updated: 12/17/2015
MalaCards based summary: Hartnup Disorder, also known as hartnup disease, is related to cystinuria and histiocytosis-lymphadenopathy plus syndrome, and has symptoms including hallucinations, cutaneous photosensitivity and muscular hypotonia. An important gene associated with Hartnup Disorder is SLC6A19 (Solute Carrier Family 6 Member 19), and among its related pathways is Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. Affiliated tissues include skin, eye and testes.
Disease Ontology:11 An amino acid metabolic disorder that iis caused by abnormalities of the renal tubules and is characterized especially by aminoaciduria involving only monocarboxylic monoamines, a dry red scaly rash, and episodic muscular incoordination due to the effects of the disease on the cerebellum.
Genetics Home Reference:25 Hartnup disease is a condition caused by the body's inability to absorb certain protein building blocks (amino acids) from the diet. As a result, affected individuals are not able to use these amino acids to produce other substances, such as vitamins and proteins. Most people with Hartnup disease are able to get the vitamins and other substances they need with a well-balanced diet.
UniProtKB/Swiss-Prot:69 Hartnup disorder: Autosomal recessive abnormality of renal and gastrointestinal neutral amino acid transport noted for its clinical variability. First described in 1956, HND is characterized by increases in the urinary and intestinal excretion of neutral amino acids. Individuals with typical Hartnup aminoaciduria may be asymptomatic, some develop a photosensitive pellagra-like rash, attacks of cerebellar ataxia and other neurological or psychiatric features. Although the definition of HND was originally based on clinical and biochemical abnormalities, its marked clinical heterogeneity has led to it being known as a disorder with a consistent pathognomonic neutral hyperaminoaciduria.
