Oct 7, 2015 · Phenylketonuria (PKU) is an autosomal recessive inborn error of metabolism caused by a deficiency in the hepatic enzyme phenylalanine hydroxylase (PAH). If left untreated, the main clinical feature is intellectual disability.

Phenylketonuria (PKU), caused by variants in the phenylalanine hydroxylase (PAH) gene, is the most common autosomal-recessive Mendelian phenotype of amino acid metabolism. We estimated that globally 0.45 million individuals have PKU, with global prevalence 1:23,930 live births (range 1:4,500 [Italy]–1:125,000 [Japan]).

Phenylalanine hydroxylase (PAH) deficiency is an inborn error of metabolism that results in elevated phenylalanine levels in blood. The classical form of the disease with phenylalanine level > 1200 µmol/L in blood is called phenylketonuria (PKU) and is …

Phenylketonuria (PKU, MIM 261,600) is a deficiency in the hepatic enzyme phenylalanine hydroxylase (PAH; EC 1.14.16.1; OMIM 612,349) that occurs in approximately 1 in 24,000 people, with an estimated 450,000 individuals affected worldwide [1].

Aug 8, 2023 · Phenylketonuria (PKU) is an inborn error of metabolism (IEM) most often caused by missense mutations in the gene encoding phenylalanine hydroxylase (PAH), which catalyzes the hydroxylation of phenylalanine (Phe) to generate tyrosine (Tyr).

May 20, 2021 · Phenylketonuria (PKU; also known as phenylalanine hydroxylase (PAH, EC 1.14.16.1) deficiency (OMIM # 261600) and Følling disease) is an inborn error of phenylalanine (Phe) metabolism, which is...

Oct 12, 2017 · Phenylketonuria (PKU; McKusick #261600) is a rare autosomal recessive inborn error of phenylalanine (Phe) metabolism caused by variants in the gene encoding phenylalanine hydroxylase (PAH). PAH normally converts Phe into tyrosine (Tyr) requiring the cofactor tetrahydrobiopterin (BH4), molecular oxygen and iron (Fig. 1) [1].

Sep 1, 2024 · This White Paper offers a neurocognitive assessment platform for clinical trials in PKU. It describes 5 neuropsychological domains relevant to outcomes in PKU. Criteria for measures to be included in the Assessment Platform are defined.

Aug 16, 2024 · Introduction: Phenylketonuria (PKU) is a genetically determined congenital metabolic disorder characterized by the body's inability to properly metabolize the amino acid phenylalanine, which is...

Dec 14, 2018 · Phenylketonuria (PKU, OMIM 261600) is a rare genetic disorder caused by pathogenic variants in the phenylalanine hydroxylase (PAH) gene, which results in elevated phenylalanine (Phe)...
