In phenylketonuria, knowledge about the relation between behavior and plasma phenylalanine is scarce. The aim of this study was to determine whether high phenylalanine is associated with disturbed behavior noticed by the patient and or close environment (parents or partners). 48 early treated PKU patients (median age 8.5, range 0-35. years)...

Background: The clinical severity of phenylalanine hydroxylase deficiency is usually defined by either pre-treatment phenylalanine (Phe) concentration or Phe tolerance at 5 years of age. So far, little is known about the course of Phe tolerance or the ability of both pre-treatment Phe and Phe tolerance at early age to predict Phe tolerance at...

In this study, we tested the hypothesis that patients with early and continuously treated phenylketonuria (PKU) are selectively impaired in cognitive functions dependent on the prefrontal cortex (PFC) over a wide age range. Thirty-six patients with PKU between 8 and 20 years of age and 36 controls matched for age, sex, and educational level of...

Background. The validity of the results of studies using retrospectively collected information on exposures is often criticized, because cases may report differently from controls even if their true exposure status is the same. This study was performed to quantify the extent to which this effect (differential misclassification) may occur for...
