Phenylketonuria: a review

Phenylketonuria: a review.

The development of a practical screening procedure for phenylketonuria and the improvement in methods of chemical analysis have led to a realization that Folling's (1934) disease of phenylketonuria is not a single entity. In this commentary, the current view on some aspects of phenylketonuria will be reviewed and the problems illustrated by experience gained in the Phenylketonuria Clinic at the...

Neuropsychological Functioning in Early-Treated Phenylketonuria - A Review

Phenylketonuria (PKU) is an inborn error of metabolism involving a deficiency of the enzyme phenylalanine hydroxylase. This condition results in elevated levels of phenylalanine and low levels of tyrosine. If left untreated, severe neuropathology and neurobehavioral sequelae manifest. The implementation of newborn screening and early dietary treatment has significantly reduced such morbidity. D...

Bone health in phenylketonuria: a systematic review and meta-analysis

Patients with Phenylketonuria (PKU) reportedly have decreased bone mineral density (BMD). The primary aim of this study was to perform a systematic review and meta-analysis to determine the extent and significance of low BMD in early treated patients with PKU. Secondary aims were to assess other bone status indicators including bone turnover markers (BTM) and to define areas for future research...

Phenylketonuria.

Phenylketonuria is the most prevalent disorder caused by an inborn error in aminoacid metabolism. It results from mutations in the phenylalanine hydroxylase gene. Phenotypes can vary from a very mild increase in blood phenylalanine concentrations to a severe classic phenotype with pronounced hyperphenylalaninaemia, which, if untreated, results in profound and irreversible mental disability. Neo...
