Why did you choose your topic.?.

I chose the topic of Phenylketonuria because it seemed really interesting 

& is a topic that not a lot of people know about.

Also, Phenylketonuria or {PKU} is a rare condition, a genetic disorder in

which the body can't process part of the protein/amino acid called Phenylalanine.

Phenylalanine{Phe} is in almost all foods, if the level is too high

 it can damage the brain & cause Cretinism.

Cretinism is when a brain & skeleton fails to develop properly

resulting in mental retardation & dwarfism.

In the image below it shows what a normal person can eat, & a person with PKU can eat.
