Sapropterin dihydrochloride for phenylketonuria [PDF]
Phenylketonuria results from a deficiency of the enzyme phenylalanine hydroxylase. Dietary restriction of phenylalanine keeps blood phenylalanine concentration low. Most natural foods are excluded from diet and supplements are used to supply other nutrients.

Phenylalanine hydroxylase mRNA rescues the phenylketonuria phenotype in mice
Phenylketonuria (PKU) is an inborn error of metabolism caused by a deficiency in functional phenylalanine hydroxylase (PAH), resulting in accumulation of phenylalanine (Phe) in patients’ blood and organs.

Pegvaliase Treatment for Adolescents With Phenylketonuria: A Multi-Site Study. [PDF]
ABSTRACT Phenylketonuria (PKU) is an inherited metabolic disorder causing elevated phenylalanine (Phe) levels and neurocognitive impairment if left untreated. While dietary therapy remains the treatment standard, adherence declines during adolescence. Pegvaliase, an injectable enzyme therapy approved for adults > 18 years in the United States, lowers ...

Age-Dependent Variation in Blood Biopterin Peaks Following Oral Tetrahydrobiopterin Administration in Phenylketonuria. [PDF]
ABSTRACT The correct diagnosis of tetrahydrobiopterin (BH4, sapropterin dihydrochloride)‐responsive phenylketonuria (PKU) and treatment with BH4 are important for prognosis and quality of life. We examined whether age affects biopterin bioavailability following oral BH4 administration in PKU and whether this influences BH4 responsiveness.
