Catalyzes the hydroxylation of L-phenylalanine to L-tyrosine
Phenylalanine hydroxylase deficiency
An autosomal recessive inborn error of phenylalanine metabolism characterized by intolerance to dietary intake of the essential amino acid phenylalanine. The disease spectrum depends on the degree of PAH deficiency and the phenylalanine levels in plasma. Severe deficiency causes classic phenylketonuria (PKU) that is characterized by plasma concentrations of phenylalanine persistently above 1200 umol/L. PKU patients develop profound and irreversible intellectual disability, unless low phenylalanine diet is introduced early in life. They tend to have light pigmentation, rashes similar to eczema, epilepsy, extreme hyperactivity, psychotic states and an unpleasant 'mousy' odor. Less severe forms of PAH deficiency are characterized by phenylalanine levels above normal (120 umol/L) but below 1200 umol/L and include moderate PKU, mild PKU, non-PKU hyperphenylalaninemia (non-PKU HPA) and mild hyperphenylalaninemia. Individuals with PAH deficiency who have plasma phenylalanine concentrations consistently below 600 umol/L on an unrestricted diet are not at higher risk of developing intellectual, neurologic, and neuropsychological impairment than are individuals without PAH deficiency.

Assessing the nutritional value and health risks of special low‑protein foods: narrative review.
Special low-protein foods (SLPFs) are essential for patients with disorders of inherited amino acid metabolism that require lifelong dietary protein restriction to prevent severe neurocognitive effects and even death. Conditions such as phenylketonuria (PKU), tyrosinemia (TYR), maple syrup urine disease (MSUD), homocystinuria (HCU), and urea cycle disorders (UCD) depend on these foods to support metabolic control and dietary adherence. SLPFs provide satiety, energy, and help prevent catabolism, but their nutritional composition poses challenges. Most SLPFs are formulated using isolated starches as the primary macronutrient base. Hydrocolloid fibers are commonly added to improve texture, consistency, shelf life, and water or gas retention. These ingredients form the backbone of SLPFs production and are consistently used across different regions worldwide, reflecting a standardized approach to their formulation. However, their potential adverse effects include suppression of gut microbiota, gut dysbiosis, increased inflammatory markers, overweight, and obesity, all of which raise cardio‑metabolic risks. Strengthening the nutritional quality of SLPFs through natural plant sources may help mitigate their potential adverse outcomes while ensuring patients’ dietary needs are met. Therefore, it is important to explore natural low‑protein alternatives that can both support sustainable food production and promote long‑term health benefits. PTS-related tetrahydrobiopterin deficiency (PTPSD) results in a lack of tetrahydropterin, an important cofactor for phenylalanine hydroxylase (PAH), tyrosine hydroxylase, and tryptophan hydroxylase. Deficiency can thus lead to neurotransmitter and neuropsychiatric disorders. The clinical spectrum of PTPSD is broad and differs according to age of onset, severity of disease, and whether preventative therapies were initiated and maintained from an early age. In the severe form, clinical symptoms may become apparent in the neonatal period and can include hypotonia, movement disorders, abnormal eye movements, autonomic dysregulation, and impaired development. Without treatment, developmental delays become more marked. Neurologic symptoms (dysarthria, dystonia, tremors, abnormal gait, parkinsonism, oculogyric crises, motor tics) may be ameliorated by treatment with sapropterin dihydrochloride and neurotransmitter precursors. Other features of the condition can include psychiatric comorbidities (ADHD, anxiety, depression), infant feeding difficulties leading to early growth failure, hyperprolactinemia, growth hormone deficiency, sleep issues, and autonomic dysfunction; many of these features can be ameliorated by appropriate treatment. In treated individuals, development often improves during adolescence, with many adults having a normal IQ level. In the mild (peripheral) form, affected individuals are usually asymptomatic apart from an increase in phenylalanine (Phe) levels. Some remain asymptomatic. However, with time, some have mild developmental delays and can develop deficiency of neurotransmitter production, such that treatment of some asymptomatic individuals may be required. The biochemical diagnosis of PTPSD is established in a proband with confirmed hyperphenylalaninemia, elevated neopterin levels, reduced biopterin levels, and a decreased biopterin-to-neopterin ratio in urine or dried blood spots (DBS) and normal dihydropteridine reductase (DHPR) activity in DBS. The molecular diagnosis of PTPSD is established in a proband by identification of biallelic pathogenic (or likely pathogenic) variants in PTS by molecular genetic testing. Targeted therapies: Immediate therapy with sapropterin (tetrahydrobiopterin dihydrochloride; BH4), a cofactor/cosubstrate of PAH, is recommended to reduce blood Phe concentrations in individuals with hyperphenylalaninemia. If sapropterin is not available, dietary Phe restriction should be implemented. Because sapropterin has limited access to the central nervous system (CNS), or rather, this access is only achieved at high doses, therapy with sapropterin does not normalize the activity of tyrosine or tryptophan hydroxylase in people with PTPSD. Additional treatment strategies are necessary for long-term management and may include the use of neurotransmitter precursors (levodopa plus decarboxylase inhibitor (DCI), i.e., carbidopa or benserazide), 5-hydroxytryptophan, and/or dopamine (rotigotine patch, pramipexole) and/or serotonin agonists, or other medications (MAO inhibitors such as selegiline) to address specific neurotransmitter deficiencies and maintain optimal neurologic function. Supportive care: Optimization of dosage and intervals of levodopa/DCI in those with abnormal movements/parkinsonism; growth hormone supplementation and/or optimization of neurotransmitter precursor therapy for growth hormone deficiency; optimization of neurotransmitter precursor therapy for recurrent hyperthermia; anticholinergic treatment may be considered for hypersalivation; standard treatment for developmental delay, spasticity, epilepsy, sleep disorders, and decreased bone mineral density. Biochemical surveillance: Routine Phe monitoring in infants (age <1 year) weekly until normalized and then every three to six months once levels normalize; every six months in children younger than age 12 years; and every six to 12 months in adolescents and adults; the Phe target ranges correspond to those of PAH deficiency. Prolactin level at each visit. Routine clinical visits with a metabolic specialist (and metabolic dietician if on Phe-restricted diet) every one to three months in infants (age <1 year), every three to six months between ages one and seven years, and every six to 12 months in those age eight years and older. General surveillance: At each visit, measure growth parameters and evaluate nutritional status; asses for new neurologic manifestations (changes in tone, seizures, movement disorders); monitor developmental progress and assess educational needs; monitor for behavioral issues (anxiety, ADHD, emotional dysregulation, depression, aggression); and assess for signs and symptoms of sleep disorders. At ages two, six, 12, and 18 years, consider neuropsychological evaluation. In adulthood, periodic parathormone levels and DXA scan. As needed, consider EEG to differentiate from movement disorder seizures. Agents/circumstances to avoid: Persons with PTPSD on Phe-reduced diet should either avoid products containing aspartame or calculate total intake of Phe when using such products and adapt diet components accordingly. Evaluation of relatives at risk: If prenatal genetic testing has not been performed, each at-risk newborn sib should be evaluated immediately (at or just after 24 hours) after birth for PTPSD using measurement of blood Phe concentration to allow for earliest possible diagnosis and treatment. If older sibs have not undergone NBS or genetic testing for the known familial pathogenic variants in PTS, measure blood Phe concentrations to clarify their disease status. Pregnancy management: Women with PTPSD who have received appropriate treatment throughout childhood and adolescence and during pregnancy may have offspring with normal intellectual and behavioral development, particularly if levels of Phe are kept in the normal range during pregnancy. Intensive clinical and biochemical supervision by a multidisciplinary team before, during, and after pregnancy in a woman with PTPSD is essential to control the symptoms of the disease, adjust the treatment if needed, and monitor the development of the fetus. If the affected woman has elevated blood Phe concentrations during pregnancy, the fetus is at high risk for maternal phenylketonuria (MPKU) syndrome (reported specifically in women who have PAH deficiency as the primary cause of their elevated Phe levels), including malformations and intellectual disability, since Phe is a potent teratogen. PTPSD is inherited in an autosomal recessive manner. If both parents are known to be heterozygous for a PTS pathogenic variant, each sib of an affected individual has at conception a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of inheriting neither of the familial PTS pathogenic variants. Children born of one parent with PTPSD and one parent with two normal PTS alleles are obligate heterozygotes. If the mother is the affected parent, MPKU syndrome is a critical issue. Females with PTPSD should receive counseling regarding the teratogenic effects of elevated maternal plasma Phe concentration (i.e., MPKU syndrome) when they reach childbearing age. Once the PTS pathogenic variants have been identified in an affected family member, carrier testing for at-risk relatives and prenatal/preimplantation genetic testing for PTPSD are possible.
The prevalence of phenylketonuria (PKU) and hyperphenylalaninemia (HPA) in Iran: a systematic review and meta-analysis.
Phenylketonuria (PKU) is one of the common Inborn Errors of Metabolism diseases, that is caused by a phenylalanine hydroxylase (PAH) deficiency or cofactor tetrahydrobiopterin. This systematic review and meta-analysis aimed to investigate the prevalence of PKU in Iran. The protocol was registered in PROSPERO (CRD42024540811). The MOOSE protocol and the PRISMA guidelines were used. The Web of Sciences, PubMed/ Medline, Sciences Direct, Google Scholar, Scopus, Civilica, IranDoc, and SID databases were searched on 31/03/2024. The I2 index and Q test were used to check heterogeneity. Comprehensive meta-analysis software (CMA ver. 2) was used (P < 0.05 is considered significant). The prevalences were reported in 100,000 neonates at national and provincial levels. Finally, 20 studies with 1,992,090 Iranian neonates were included. The prevalence of screen-positive cases was 75.6 (95% CI: 48.1-118.72). The prevalence of confirmed PKU was 16.7 (95% CI: 13.6- 20.5); this prevalence in girls and boys was 15.2 (95% CI: 5.2-44.2) and 9.8 (95% CI: 3.2- 29.8), respectively. 53% of the cases had Hyperphenylalaninemia (HPA). The prevalence of HPA and classical PKU was estimated at 8.9 (95% CI: 5.9-13.41) and 8.0 (95% CI: 5.1-12.59), respectively. Subgroup analysis was performed based on region, province, and study quality to discover the source of heterogeneity. In addition, mixed effects meta-regression was used to find the relationship between continuous variables. Sensitivity analysis showed that the pooled estimate was robust. It seems that the screening program in Iran was effective and detected almost all PKU cases in the first few days of their lives. This information showed that the PKU prevalence is relatively higher than in most parts of the world, thus their prevalence should be controlled.
Brain Age in Adult Patients With Early-Treated Phenylketonuria.
Structural brain alterations have been observed in individuals with phenylketonuria (PKU); however, the potential impact of PKU on brain aging remains unexplored. This study investigated brain age in adults with early-treated classical PKU compared to healthy controls. Thirty early-treated adults with classical PKU (age 19-48 years) and 59 age-, sex-, and education-comparable healthy controls underwent structural magnetic resonance imaging (MRI), cognitive and mood assessment, and blood sampling. Brain age was estimated using machine learning models trained to predict brain age from MRI-derived features across the full brain, cortical lobes, or subcortical regions. The brain age gap (BAG)-the difference between brain age and chronological age-was calculated. In addition, white matter lesion load was rated in patients. While patients with PKU showed differences in BAG for four out of eight brain age estimates, only the BAG in the insula was significantly higher in PKU than controls after correcting for multiple comparisons (puncor = 0.006, η2 = 0.07). The cingulate BAG was positively associated with concurrent and historical Phe levels (rs = 0.41-0.69, puncor < 0.05) and with white matter lesion load (rs = 0.40, puncor = 0.034). Further, subcortical and cingulate BAG were linked to cognitive performance (rs = -0.41-0.38, puncor < 0.05). These correlations did not survive FDR-correction. In conclusion, the elevated insular BAG in adults with early-treated PKU may reflect atypical brain development due to cumulative effects of early-life or lifelong metabolic disturbances. Longitudinal studies are warranted to elucidate brain aging trajectories and their cognitive implications in PKU.
