A prospective, open-label study of PKU Sphere in patients with PKU following a phenylalanine restricted therapeutic diet.
The primary objective of this trial is to evaluate the safety and tolerability of long-term Phenoptin treatment in subjects with PKU.
Conduct a prospective, longitudinal study to evaluate nutritional status in adults with phenylketonuria (PKU) before and during treatment with pegvaliase (Palynziq™).
This study aims to measure changes in participants' blood phenylalanine (Phe) levels in participants with PKU when switching from a conventional amino acid based protein substitute to a GM...
Conduct a cross-sectional analysis of the nutritional status of individuals with PKU treated with pegvaliase for greater than one year. We will evaluate laboratory markers of nutritional s...
An enzyme of the oxidoreductase class that catalyzes the formation of L-TYROSINE, dihydrobiopterin, and water from L-PHENYLALANINE, tetrahydrobiopterin, and oxygen. Deficiency of this enzyme may cause PHENYLKETONURIAS and PHENYLKETONURIA, MATERNAL. EC 22.214.171.124.
A group of autosomal recessive disorders marked by a deficiency of the hepatic enzyme PHENYLALANINE HYDROXYLASE or less frequently by reduced activity of DIHYDROPTERIDINE REDUCTASE (i.e., atypical phenylketonuria). Classical phenylketonuria is caused by a severe deficiency of phenylalanine hydroxylase and presents in infancy with developmental delay; SEIZURES; skin HYPOPIGMENTATION; ECZEMA; and demyelination in the central nervous system. (From Adams et al., Principles of Neurology, 6th ed, p952).
