Phenylketonuria management from an European perspective: A commentary

Phenylketonuria is discussed from an European perspective, addressing the need of common definitions of terms commonly used, the need of a world-wide guideline on the diagnosis and treatment of phenylketonuria, the differences between existing European guidelines, and day-to-day care, further directives for the near future, and changing the concept from compliance to concordance, in which patients have a more clearly defined responsibility.
