Archives of Disease in Childhood. Because of the relatively large number of different alleles and the expected consequences of compound heterozygosity, one can account for the broad spectrum of individual phenotypes observed in France.

They no longer needed dietary restriction and showed normal development after 2 years. Amino Acid Metabolism and Genetic Variation. The average number of new cases of PKU varies in different human populations.

Patients with “hyperphe” may have more functional PAH enzyme and be able to tolerate larger amounts of phenylalanine in their diets than those with classic PKU, but unless dietary intake is at least somewhat restricted, their blood Phe levels are still higher than the levels in people with normal PAH activity.

Clinical significance of brain phenylalanine concentration assessed by in vivo proton magnetic resonance spectroscopy in phenylketonuria. The sweetener aspartamepresent in many diet foods and soft drinks, must also be avoided, as aspartame is metabolised into phenylalanine.
