Phenylketonuria (PKU) can be defined as a rare metabolic disorder caused by a deficiency in the production of the hepatic (liver) enzyme phenylalanine hydroxylase (PAH). PKU is the most serious form of a class of diseases referred to as hyperphenylalaninemia, all of which involve above normal (elevated) levels of phenylalanine in the blood.
Phenylketonuria (PKU) (phenyl + ketone + -uria; /ËfinÉlËkitÉµnËjÊÉriÉ/) is an inborn error of metabolism involving impaired metabolism of phenylalanine, one of the amino acids.Phenylketonuria is caused by absent or virtually absent phenylalanine hydroxylase (PAH) enzyme activity.n people without PKU, the PAH enzyme breaks down any excess phenylalanine from these sources beyond what is needed by the body. However, if there is not enough of the PAH enzyme or its cofactor, then phenylalanine can build up in the blood and brain to toxic levels, affecting brain development and function.
