GARD Rare
Mondo Description Hartnup disease is a rare metabolic disorder belonging to the neutral aminoacidurias and characterized by abnormal renal and gastrointestinal transport of neutral amino acids (tryptophan, alanine, asparagine, glutamine, histidine, isoleucine, leucine, phenylalanine, serine, threonine, tyrosine and valine).
Uniprot Description 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.
Disease Ontology Description An amino acid metabolic disorder that is 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.
