hi i am 23 and i have pku though i am not sure which kind. i was wondering have u been on diet ur whole life from birth? i didnt know that people with pku could be slow. i am just like any other person looking at me u would never know i was different. i have a job and i am finishing up college. i dont know much about pku other then the basics. i would love to learn more about maternal pku since i really havent heard much about it. i am here if u ever want to chat.
