Recent studies show that high phenylalanine levels above about 14-15 mgdl 840-900 moll in PKU patients who have the more serious forms of the genetic defect may cause continued neurological damage in adulthood.

PKU is characterized by reduced activity of the liver enzyme phenylalanine hydroxylase which metabolizes the amino acid phenylalanine one of the building blocks of proteins. Classical PKU results from impaired activity of the liver enzyme phenylalanine hydroxylase which converts phenylalanine phe to tyrosine. Patient genotypes help in predict.
Loss-of-function of PAH leads to accumulation of phenylalanine in the bloodbody of an untreated patient which damages the developing brain causing severe mental retardation. Behavioral and emotional problems. Untreated PKU leads to mental retardation.
