Overview

Classification

Subtypes of phenylketonuria

According to Phe levels PKU can be classified as:[1] [2]

  • Mild (mPKU): < 360 μmol/L
  • Moderate (moPKU): 360–1200 μmol/L
  • Classical (cPKU): >1200 μmol/L

Maternal phenylketonuria

Maternal Phenylketonuria (MPKU)[3] is a complication of PKU, caused by the teratogenic effects of high levels of Phe in the fetus. MPKU was first described by Charles Dent in 1956.
