Sorry, yes the difference between hyperphe and classical PKU is how much phe a person can tolerate. People who have hyperphe are usually allowed much more phe then those with classical PKU. I didn’t know the difference between classical PKU and hyperphe until I was 12 and heard somebody mention it online and I asked my doctor which one I am. I’m Classical PKU. nBreanna
