Introduction:In patients with phenylketonuria protein rich-foods are restricted. Milk, dairy products, meat and fish are replaced by phenylalanine-free (phe-free) metabolic formula. Therefore patients with phenylketonuria may be at risk for protein deficiency and zinc deficiency. Aim of this study was to assess Plasma zinc status, and zinc intake in Patients with phenylketonuria Undergoing Ther...
Atypical phenylketonuria among infants with hyperphenylalaninemia must be promptly diagnosed and differentiated from classical phenylketonuria, because these patients require different treatment to prevent irreversible neurological damage. Measurement of pteridines in urine by liquid chromatography has been widely used for this purpose. Here we report a rapid, simplified liquid-chromatographic ...

The case histories are reported of three patients with phenylketonuria (PKU) in whom the initial Guthrie screening for PKU was falsely negative. Possible explanations for this problem are reviewed, as well as the limited cost-effectiveness of general re-testing. Guidelines are suggested to im prove the sensitivity of PKU screening procedures for newborns.
PCR amplification, either conventional, or as site directed mutagenesis using primers with mismatched 3'-ends, followed by restriction endonuclease digestion, provides rapid, non-isotope assays of known mutations in the human phenylalanine hydroxylase gene. Such assays were shown to have the potential to detect all of the 18 presently reported phenylketonuria mutations. The practical applicabil...
The results of the International Collaborative Study of Maternal phenylketonuria have shown that dietary phenylalanine restriction of women with hyperphenylalaninemia during pregnancy decreases the incidence of mental retardation, microcephaly, congenital heart disease, and intrauterine growth retardation in their offspring. The best results are achieved when treatment is initiated before conce...
Galactosaemia, phenylketonuria and homocystinuria are inborn errors of metabolism as the term was defined by Garrod (1908). I n all three lack of an enzyme causes a metabolic block and accumulation of the substrate of the missing enzyme, and all three are inherited as Mendelian recessive characters. Unlike Garrod's original examples, galactosaemia, phenylketonuria and homocystinuria are often a...
OBJECTIVE The objective of this work was to determine whether cells overexpressing phenylalanine (Phe) hydroxylase (PAH) can significantly reduce Phe in vitro for potential use as a therapy for preventing maternal phenylketonuria. STUDY DESIGN Human 293T and WRL68 cell lines were transiently and stably transfected to overexpress PAH. Cells were encapsulated within microspheres of sodium algin...
