Hartnup´s Syndrome


Rare hereditary recessive disorder characterized by a pellagrous rash, cerebellar ataxia, mental retardation and renal aminoaciduria due to a defect in the cellular transport of neutral amino acids. The cutaneous signs precede the neurological manifestations. The rash is dry, scaly and well marginated, affecting the light-exposed areas. After exposure to sunlight the skin reddens and an exsudate may occur.
