Background: Untreated maternal phenylketonuria or hyperphenylalaninemia may result in nonphenylketonuric offspring with neonatal sequelae, especially intellectual disability, microcephaly, and congenital heart disease (CHD). Dietary treatment to control phenylalanine concentrations can prevent these sequelae. Objective: We aimed to present an overview of reported pregnancy complications and neo...

Early-treated phenylketonuria (PKU) is associated with a range of neuropsychological impairments. Proposed mechanisms for these impairments include dopamine depletion and white matter pathology. Neuroimaging studies demonstrate high-signal intensity in the periventricular white matter in most PKU patients, which can extend into subcortical and frontal regions in more severe cases. A review of h...

background: phenylketonuria (pku) is an autosomal recessive disease of phenylalanine metabolism that brings deficiency of the enzyme phenylalanine hydroxylase (pah). early diagnosis is very important to prevent complications. this study was designed to describe characteristics of patients with phenylketonuria in mazandaran province in northern iran. methods: we studied 24 cases suffering from p...

Visual evoked potentials (VEP) were measured in 36 patients with early-treated phenylketonuria (PKU; aged 1 to 11 years) and good metabolic control before and after supplementation with omega-3 long-chain polyunsaturated fatty acids (LC-PUFA) from fish oil. Patients with PKU had significantly longer P100 latencies than 22 age-matched control subjects. After 3 months of LC-PUFA supplementation, ...
