Blue diaper syndrome
|Blue diaper syndrome|
|Classification and external resources|
It is caused by a defect in tryptophan absorption. Bacterial degradation of tryptophan in the intestine leads to excessive indole production and thus to indicanuria which, on oxidation to indigo blue, causes a peculiar bluish discoloration of the diaper. Symptoms typically include digestive disturbances, fever and visual problems.
It was characterized in 1964.
Blue diaper syndrome is thought to be inherited as an autosomal recessive disorder.
