Hyperphenylalaninemia is the high presence of phenylalanine in the system/blood caused by a genetic mutation. In this case a missense error in the gene which encodes GTP cyclohydrolase. Consequently, this form of hyperphenylalaninemia is also called GTP cyclohydrolase I deficiency and/or dopa-responsive dystonia. It is an autosomal recessive mutation.
The mutation results in a reduction in the production of BH4 which is a necessary component in the reaction which transforms phenylalanine to other products in the body.
Common symptoms include: abnormality of eye mpvement, choreoathetosis, dysphagia, dystonia, excessive salivation, hypekinesis, lethargy, limb hyptertonia, seizures, tremor, among others.
