For a child to inherit PKU, both parents must have and pass on the defective gene. [17] If both parents are carriers for PKU, there is a 25% chance any child they have will be born with the disorder, a 50% chance the child will be a carrier and a 25% chance the child will neither develop nor be a carrier for the disease.

Persons with genetic predisposition to PKU have normal mental development on this diet. Previously, it was thought safe to withdraw from the diet in the late teens or early twenties, after the central nervous system was fully developed; recent studies suggest some degree of relapse, and a continued phenylalanine-restricted diet is now recommended.
Untreated PKU results in irreversible neurological damage. [1] After the discovery of PKU as a cause of mental retardation, Horst Bickel and colleagues discovered that it could be treated successfully with a diet low in phenylalanine. [7] The main drawback in successful treatment of PKU was the delay in identifying affected individuals.
To provide a basis for improving the understanding of the epidemiology, genotype/phenotype correlation and outcome of these diseases and their impact on the quality of life of patients, and for evaluating diagnostic and therapeutic strategies a patient registry was established by the noncommercial International Working Group on Neurotransmitter ...
The E.S.PKU benchmark report [5] assesses the differences in care across Europe and provides a starting point for the E.S.PKU to improve any gaps in care that have been identified. [6] In consequence, the delegates decided that action is required to improve this situation. The report was presented [7] at the European Parliament. To underline ...
Inborn errors of metabolism form a large class of genetic diseases involving congenital disorders of enzyme activities. [1] The majority are due to defects of single genes that code for enzymes that facilitate conversion of various substances into others . In most of the disorders, problems arise due to accumulation of substances which are ...
D.A.R.E. warns that the risky situations depicted in the teen drama starring Zendaya bring “potential negative consequences” to the real-life teens who watch it. Here's what other experts say.
The compound exists in equilibrium with its (E)- and (Z)-enol tautomers.[citation needed] It is a product from the oxidative deamination of phenylalanine.When the activity of the enzyme phenylalanine hydroxylase is reduced, the amino acid phenylalanine accumulates and gets converted into phenylpyruvic acid (phenylpyruvate), which leads to 'Phenylketonuria (PKU)' instead of 'tyrosine' which is ...
