PKU

(Pku)This stands for Phenylketonuria. This is a disease  that creates some kind of genetic disorder characterized by a deficiency in the hepatic enzymes. The enzyme is necessary to metabolize the amino acid phenylalanine. Usually they do screening for this in new born babies. The reason this is so bad is because it can create brain damage and if not taken care of or treated properly its progressiveness will create mental retardation. Later studies said that a healthy diet can help but in recent studies show that  in worse cases you need protein supplements and need to lower phe levels to safe range.
