Phenylketonuria (PKU) is an autosomal recessive genetic disorder characterized by a deficiency in the enzyme phenylalanine hydroxylase (PAH). This enzyme is necessary to metabolize the amino acid phenylalanine to the amino acid tyrosine. When PAH is deficient, phenylalanine accumulates and is converted into phenylpyruvate (also known as phenylketone), which is detected in the urine. PAH is found on chromosome number 12.
Left untreated, this condition can cause problems with brain development, leading to progressive mental retardation and seizures. However, PKU is one of the few genetic diseases that can be controlled by diet. A diet low in phenylalanine and high in tyrosine can be a very effective treatment. There is no cure. Damage done is irreversible so early detection is crucial.
FYI::: Look on the back of ALMOST EVERY ARTIFICIALLY SWEETENED PRODUCT, INCLUDING DIET SODA- IT WILL SAY WARNING: THIS PRODUCT CONTAINS PHENYLALANINE!! Too much of this stuff isn't good for anyone, especially diabetics that THINK they're not eating sugar, when in fact, these sweeteners still cause a glucose-insulin response!!!
You can find more information on the web by typing in PKU
