Living with Mild phenylketonuria
A milder form of PKU, an inherited condition in which the body cannot properly break down an amino acid called phenylalanine.
Understanding Mild phenylketonuria
In mild PKU, blood phenylalanine levels are 600 to 1,200 micromol/L. Signs include reduced thinking skills and behavior and developmental differences. The enzyme that breaks down phenylalanine (phenylalanine hydroxylase) is somewhat active, compared with classic PKU, where it is missing or nearly missing.
