Benign Hyperphenylalaninemia (H-PHE)

 

Benign Hyperphenylalaninemia (H-PHE) is a mild form of phenylketonuria. It is considered an amino acid condition because people with H-PHE have problems breaking down phenylalanine, an amino acid which is a building block of proteins. Most people with this condition experience mild or no symptoms. Some individuals benefit from dietary intervention.

This condition is also known as Hyper-PHE, non-phenylaketonuria - mild type, variant hyperphenylalaninemia, PKU variant, hyperphenylalaninemia, hyperphenylketonuria.
