Hydroxyprolinemia

Hydroxyprolinemia is an inherited metabolic condition characterized by elevated levels of the amino acid hydroxyproline in the blood and urine. This condition usually does not cause physical or cognitive abnormalities. Hydroxyprolinemia was initially described in association with intellectual disabilities; however it has also been reported in cognitively normal individuals and is thus thought to be begnin. Hydroxyprolinemia is thought to be an autosomal recessive condition.
